How To Add Flutter Into Existing iOS and Android Apps? 2024 [Updated]

Rebuilding an existing application using Flutter is long and long. In these situations, Flutter can be integrated and fragmented into existing applications as a module or library. It is then possible to import this module into the Android or iOS app to render a part of your application’s interface using Flutter.

It is easy to rebuild your Flutter application in just a few steps.

This add-to-app feature allows the integration of multiple screens of any size. This could be useful in situations like an ad-hoc navigation stack that has dual Flutter and native screens or pages with several Flutter view views that are partially screened.

Multiple Flutter instances allow each one to keep an entirely separate application and UI state while using a minimal amount of memory resources. Learn more on the Multiple Flutters pages.

Integrating Flutter or adding it to existing Android apps is necessary as we move into the age of applications that are cross-platform and in high demand. But, it needs the use of a specific method for your application. This is why it needs to be planned with a suitable solution, and also compatible with the same for existing Android apps. Another way to do this is moving your existing Android app to Flutter. This is a single platform-to-cross-platform migration because Flutter is a cross-platform framework.

Flutter allows us to build customized applications that work on Android or iOS. With Flutter, the Flutter application, we can integrate the modules that comprise our Flutter project with any existing local ventures. Once we’ve coordinated Flutter, we can coordinate the Flutter initiative, we can help to develop the rest part of the Shudder application that will naturally be integrated into our parent project.

Add Flutter to an existing iOS and Android Application

You can integrate Flutter into Android as well as iOS apps using the simple steps listed below. Let’s begin with the Android application!

Add Flutter Into Existing Android App

  • Auto-build and then import Flutter into your Flutter module by including a Flutter SDK hook into the Gradle script.
  • Create your Flutter module as a generic Android Archive (AAR) to integrate into your build system and to improve Jetifier integration with AndroidX.
  • FlutterEngine API for starting and persisting your Flutter environment independently of attaching a FlutterActivity/FlutterFragment etc.
  • Android Studio Android/Flutter collaborative editing and wizards for creating and importing modules.
  • Java, as well as Kotlin host applications, are supported.
  • Flutter modules can make use of the Flutter plug-ins to connect to the platform.
  • The Flutter Debugging feature is available as well as stateful hot reloads by making use of the flutter attach IDEs and the command line for connecting to an app that contains Flutter.

Add Flutter Into Existing iOS App

  • Automate the build and import of Flutter by including the Flutter SDK hook to your CocoaPods and also to Your Xcode construction phase.
  • Make your Flutter module an existing iOS Framework for integration into your build system.
  • FlutterEngine API for starting and persisting your Flutter environment independently of attaching a FlutterViewController.
  • The Objective-C as well as Swift host applications are supported.
  • Flutter modules can use the Flutter plug-ins to communicate with the platform.
  • The Flutter Debugging feature is available as well as hot reloading with stateful states through Flutter Attach IDEs and the command line for connecting to an app that contains Flutter.

Incorporate Flutter into a currently running Android application

Naturally, Flutter permits us to accomplish several things that were previously integrated into Android applications. These can be explained under. This module creates wizards that allow co-altering Android ventures and Flutter applications within Android Studio. It supports two kinds of software, Kotlin as well as Java.

If we’ve integrated Flutter in a coordinated manner, it may also use shutter joins to the ID to connect Flutter with your application. It will coordinate and adjust to the modules of Flutter as well as the Flutter modules can be coordinated consistently.

If we include the shudder SDK snares in our Gradle record, it automatically constructs the Flutter modules that we’ve created. Additionally, it permits the major Shudder modules to work together and change to the previous stage, and how Flutter components are then seamlessly integrated into the previous stage.

1. Code and Implementation

Flutter gives Flutter. Activity is a part of the Android application which recreates the shudder experience. We’d like to include Flutter action in AndroidManifest.xml. It is recommended to execute it within your code in a separate manner:

In the beginning, it is necessary to add Action. Primary. A button was created in XML with both the ID and name of the button identified, which can assist us in performing any action on the button.

Then, we’ll define the android action within buttons in the main movement class which is responsible for coordinating the Flutter project within the android app. It can keep up with its obligations such as showing the sprinkle screen of Flutter and Android. The code is described within the source code, Flutter can do the existing tasks and handle these tasks.

Flutter can be integrated into your existing Android application in a piecemeal fashion, either as a Source code Gradle subproject or in AARs. The combination stream is accessible via an Android Studio editor and the Shudder module, or physically.

2. Utilizing Android Studio

Its Android Studio IDE is a valuable way to integrate the Flutter module. With Android Studio it is possible to combine the Android code and Shudder code to accomplish the same job. It is also possible to continue using the standard functions of the IntelliJ Flutter module such as Dart code completion, hot reload as well as gadget auditor.

Add-to-application streams that are supported by Android Studio are just upheld by Android Studio 3.6 with variant 42+ of the Shudder module available in IntelliJ. This Android Studio combination likewise just allows coordinating with the sources script Gradle subproject, in contrast to using AARs. Below are more specifics about the requirements.

By using this Register > New, New Module… menu within Android Studio in your current Android project, you could create a new Flutter module to coordinate or choose an existing Shudder module you created before the time you made it.

3. Manual reconciliation

To connect a Flutter module with an existing Android app physically but without making use of the Flutter Android Studio component, use these steps:

4. Include the Android module in a Flutter app

Add the Shudder module based on your application currently to Gradle. There are two options for getting this done. The Flutter app integrates tools that make Android AAR non-exclusive intermediaries that can be bundled with the Flutter module.

This is great if downstream developers of your application prefer not to have the Flutter SDK added. It is a form step that you can add if you build a lot often.

The subproject for source code can be a useful single-tick fabrication process, but this requires Flutter SDK. This is the platform used for Android Studio. Android Studio IDE module. In the following steps, you can include Flutter in the Android and iOS apps. It is recommended to start by using Flutter for the Android application!

Flutter is now a part of the Android Application

  • Create a new Android project
  • Include a new flutter module in your application
  • Include a dependency in building apps that is part of the host application
  • Auto-construct and then import to the Shudder module, by adding the Flutter SDK Snare in your Gradle script.
  • Integrate your Flutter application into a traditional Android Document (AAR) for integration into your form framework, and improved Jetifier compatibility with AndroidX.
  • Flutter Engine Programming interfaces for freely beginning and persevering your Shudder climate by connecting a FlutterActivity/FlutterFragment and so on.
  • Android Studio co-altering Android/Flutter and module import wizard
  • Flutter modules may be able to utilize Shudder modules to work with the stage
  • Native to Android project is now successfully integrated with Flutter.
