He will guide you through the process of integrating SDKs, accessing native functionalities, and creating a seamless bridge between Flutter and the native platform.&nbsp; Let's start with what an SDK is.&nbsp;<h2 class="heading-node" id="q0pkxgv2y" style="text-align: justify">What is SDK?&nbsp;</h2>Software Development Kit (SDK) or devkit is a set of software tools and programs that developers use to create applications for specific platforms.&nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/06/Android-SDK-Integration-Blog-Banner-Design-05.webp" alt="M2P Fintech" title="" width="100%" height="348">SDK is like a magical toolbox that comprises everything a developer needs to bring their app ideas to life on a particular platform. This toolbox includes libraries, documentation, code samples, processes, and guides that developers can use and integrate into their own apps.&nbsp;&nbsp; SDKs are created to be used for particular platforms or programming languages.&nbsp; When developing an Android application, you would require an Android SDK toolkit, while an iOS SDK would be necessary for building an iOS app. &nbsp; Similarly, a VMware SDK would be essential if you intend to integrate with the VMware platform. Likewise, a Nordic SDK would be the appropriate choice for developing bluetooth or wireless products. The specificity of SDKs ensures developers have the tools tailored to their intended platform or technology.&nbsp; Now, let’s see how SDK is integrated into Flutter.&nbsp;&nbsp;<h2 class="heading-node" id="3jyfvdfuq" style="text-align: justify">SDK Integration into Flutter&nbsp;</h2>SDK integration in Flutter involves integrating external development kits into your Flutter project. These SDKs are pre-built libraries or tools offering additional features or services not native to the Flutter framework. &nbsp; They are developed in different programming languages like Dart, Swift, Objective-C, Java, or Kotlin. Incorporating these SDKs into your Flutter project allows you to access extended functionality and leverage existing libraries and tools to enhance your app development process.&nbsp; SDK integration enables you to create a feature-rich, dynamic, and user-friendly app. Built on multiple programming languages, they are compatible with different platforms.&nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/06/Android-SDK-Integration-Blog-Banner-Design-04-1.webp" alt="M2P Fintech" title="" width="100%" height="358">SDK integration in Flutter enables developers to leverage native platform features, tap into third-party services, and extend the capabilities of their applications.

This bidirectional communication mechanism facilitates data exchange and functionality between Flutter and the native platform.&nbsp; &nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/06/Android-SDK-Integration-Blog-Banner-Design-06.webp" alt="M2P Fintech" title="" width="100%" height="360">Within the Flutter/services package, you'll find the Method Channel class, crucial in establishing a communication channel between your Flutter app and the native platform. This channel facilitates the invocation of methods and the handling of results, enabling seamless interaction between Flutter and the underlying native platform.&nbsp; Let's see how the code is integrated into Flutter. To integrate SDKs using Method Channels in Flutter, there are a few steps to be followed on both the Flutter side and the native (Android and iOS) platform side.&nbsp;&nbsp; First, let’s see the flutter side.&nbsp;<h2 class="heading-node" id="iah66oac6" style="text-align: justify">Flutter&nbsp;</h2>To use the Method Channel in Flutter for SDK integration, here is the fundamental structure for creating and invoking a Method Channel in Flutter and iOS.&nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/06/MicrosoftTeams-image-15.webp" alt="M2P Fintech" title="" width="100%" height="508"><h2 class="heading-node" id="v9wvbfq7n" style="text-align: justify">Native (Android + iOS)</h2>On the native side (iOS), specifically inside the AppDelegate file, you would typically implement the Method Channel functionality. This is where you handle method invocations from the Flutter app and establish communication between Flutter and the iOS platform.&nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/06/MicrosoftTeams-image-18.webp" alt="M2P Fintech" title="" width="100%" height="1422">The following is the basic structure for creating and invoking a Method Channel in Flutter and iOS:&nbsp;<h2 class="heading-node" id="oo9beyl71" style="text-align: justify">Android&nbsp;</h2>On the Android native side (MainActivity.kt), you can set up the Method Channel.<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/06/MicrosoftTeams-image-20.webp" alt="M2P Fintech" title="" width="100%" height="84">To integrate the SDK on the Android side, you need to perform the following steps:&nbsp; Step 1: Add the AAR file to your project: Navigate to the project directory: Project → android → app → lib (create the "lib" directory if it doesn't exist).&nbsp; Place the AAR file inside the "lib" directory&nbsp; Step 2: Modify the build.gradle file (app level):&nbsp; Open the build.gradle file located at: Project → android → app → build.gradle.&nbsp; Step 3:&nbsp; And need to add the required dependencies for SDK integration (mentioned in the SDK documents)&nbsp;<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2023/06/MicrosoftTeams-image-16.webp" alt="M2P Fintech" title="" width="100%" height="731">You will need to do the following to incorporate this functionality into your Flutter app.&nbsp; Step 1: Review the SDK Integration Document provided by the SDK developer before proceeding with the implementation. This document contains essential information and instructions on how to integrate the SDK into your application effectively.&nbsp; Step 2: If the SDK Integration Document specifies any required API calls and data retrieval, it is essential to follow those instructions. These API calls will enable you to fetch the necessary data to be passed as arguments to the SDK integration scenario.&nbsp; Step 3: To pass values from Flutter to iOS after retrieving them via an API call, you need to write an API call function in Flutter. This function will make the necessary HTTP requests and fetch the required data. Once the data is obtained, you can pass it as arguments to the SDK integration in Flutter. These arguments will be subsequently sent from Flutter to the iOS platform.&nbsp; By following these steps and carefully reviewing the SDK Integration Document, you can successfully incorporate the required API calls and data retrieval processes into your Flutter app, ensuring smooth integration with the SDK.&nbsp; So, whether you're a seasoned developer or just starting your Flutter journey, don't hesitate to explore the vast world of SDKs and the Method Channel.&nbsp;&nbsp; Happy Coding and Integrating&nbsp; Do you have any questions or suggestions?&nbsp; Write to us at <a class="link" href="mailto:business@m2pfintech.com">business@m2pfintech.com</a>.

It has radically simplified financial services and processes with the help of banking applications. Back in the day fintech applications were confined only to tech-savvy users, but today, it has become an integral part of life for all generations. The appetite for mobile-first, customized financial applications is driving fintech companies to innovate and consistently deliver advanced products and services.Banking applications are traditionally built for specific operating systems and <a class="link" href="https://m2pfintech.com/blog/api-the-power-that-drives-new-age-banking-ecosystems/">APIs</a> using the respective native programming languages/technologies. But these practices resulted in higher cost implications and prolonged time to market. To overcome such limitations, fintechs adopted the latest digital innovations to power personalization, user engagement, and security.The launch of Flutter in 2017 changed the dynamics of application development as it provided a great user experience tailored for specific operating systems. This unique feature made Flutter the holy grail of fintech app development. Over the last few years, several companies have successfully launched their applications using the Flutter framework.Curious to know how to add a flutter module to an existing android and iOS application?You’re in luck. We have our domain expert and Senior Software Engineer,&nbsp;<a class="link au lh" href="https://www.linkedin.com/in/chinnadurai-viswanathan-b2b6b7a5/" target="_blank" rel="noopener ugc nofollow">Chinnadurai Viswanathan</a>&nbsp;share the nitty-gritty of how Flutter can be used in fintech applications.Here are the topics he sheds light upon.<a class="link" href="#430e">What is Flutter?</a><a class="link" href="#d14a">Why Flutter is critical to Fintech?</a><a class="link" href="#fb14">How to Generate a Flutter Module?</a><a class="link" href="#69a3">Android Integrations</a><a class="link" href="#af8c">IOS Integrations</a>Here you go!<h2 class="heading-node" id="ag0mm47r9">What is Flutter?</h2>Flutter is an open-source software development kit from Google. It is used to build cross-platform applications, including mobile, web, and embedded products &amp; services. Programmers employing Flutter write a single codebase to create applications that run across various platforms such as android, iOS, Windows, and Linux. Developers build a Flutter app once and cross-compile them for multiple platforms with Flutter instead of creating an individual application for each platform.Let us be clear here that Flutter is not a programming language. It is a User Interface (UI) framework that works on the Dart programming language. It uses native UI elements which can be personalized during development. Some of the most used Flutter applications are Google Pay, Xianyu by Alibaba, and the KenKen puzzle app.<h2 class="heading-node" id="d14a">Why is Flutter critical to Fintech?</h2>Flutter combines the best features from native and hybrid application development approaches. Therefore, it is considered an optimal solution for neo banks and fintech companies. The Flutter framework offers manifold benefits to the user. But in this article, we emphasize the ones that are most essential for developing a fintech or mobile banking solution. Application and Data SecurityFlutter is powered by Dart and compiled into a native, computer-executable code. There are no intermediary apps required. This makes Flutter-based banking apps more secure than native solutions. Moreover, it also involves a comprehensive native library and changes data formats during compilation. So, the reverse engineering process is multifaceted, making it almost impossible for hackers to comprehend the software functionality to reproduce.Information security and compliance with regulations like <a class="link" href="https://m2pfintech.com/blog/pci-dss-the-payments-armour/">PCI DSS</a> and GDPR are imperative for a banking application. The framework allows biometric authentication via Face ID or Touch ID, and enables Dart developers to leverage the recently released library implementations of all popular data encryption algorithms. This boosts the security of the customers’ personal and financial data as well as transaction details.Reliable PerformanceAn application’s performance is directly proportional to customer engagement and retention rate. Delays in loading time significantly impact the product’s performance, which can make the customers stop using the application again.Flutter can offer up to 120 frames per second (FPS) performance, making it a top choice for banking apps that serve a colossal userbase with rapid response time.Use of Declarative APIFlutter harnesses reactive declarative UI <a class="link" href="https://m2pfintech.com/blog/api-the-power-that-drives-new-age-banking-ecosystems/">APIs</a>. This means Flutter’s user interface reflects the current state of the application. For example, if a user flips a switch in the settings screen, it triggers a redraw of the current state, and the UI rebuilds from scratch. This is the key advantage of Flutter.There is only one code path for any state of the user interface. The developer describes what the UI should be like, for any given state once, and that is it. The framework handles the arduous, error-prone task of optimizing the UI.Saves Time, Cost, and EffortUnlike native technologies, the Flutter framework presents a unique feature called the&nbsp;Hot Reload. It allows the developers to see the front-end and back-end changes in real-time. This enhances the product delivery speed as it saves a lot of time involved in developing and compiling a banking app. Additionally, Flutter offers a lot of widgets that help in simulating the behavior of various design languages, thus enabling the developers to jump some of the tedious steps in the application development.Furthermore, by using Flutter, developers write only one codebase for different operating systems. Thus multiple teams for each operating system is not required. This reduces the time and effort involved in testing bugs and potential issues. Furthermore, the use of a single codebase for different platforms drastically alleviates the maintenance process and, in turn, minimizes operational costs.Delivers Seamless User Experience and PerformanceReleasing new features and updates according to end-user feedback is the key to boosting customer engagement and retention. Flutter is flexible and has an in-built application builder. The developers can take advantage of a wide range of pre-developed, reusable UI elements to customize and fit customer needs and specifications.

In case you are using the stable channel, change/ upgrade your channel before moving to the next step. Now, create a flutter module as shown in the below image.<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com/m2p-website-file/marketing-cms/m2p-blog/2022/06/01.webp" alt="M2P Fintech" title="" width="100%" height="284">Upon clicking the finish button, a flutter module will be generated in the chosen folder.Now, using flutter design, you can make any design to meet your business requirements.Let us take the below design as an example<img src="https://m2p-website-file.s3.ap-south-1.amazonaws.com//m2p-website-file/marekting-cms/m2p-blog/2025/05/02.webp" alt="Flutter" title="" id="50luuo7xe" width="100%" height="284"><h2 class="heading-node" id="69a3">How to add Flutter to Android?</h2>We will first create a new Android Studio project.Step 1: Start&nbsp;Android Studio&nbsp;on your system.Step 2: Click on&nbsp;Start a new Android Studio projectStep 3: Choose&nbsp;Empty Activity/Whatever you need (Based on your business logic)&nbsp;and click&nbsp;Next.Step 4: Now enter the details for your&nbsp;native android projectStep 5: Click on the Finish buttonThere are two ways to implement the Flutter Module:(1) Using Android Archive (ARR)(2) Using Module’s source codeHere, we are using the Module’s source code as it facilitates a one-step build for the Android and Flutter projects. It is also convenient to work simultaneously on both parts; however, remember to install the Flutter SDK to build the host app.As the next step, add the Flutter module as a sub-project to the host app’s settings.
