Flutter has made it quite easy to develop complex UIs for developers.
Flutter is a very performant app development framework that is written in Dart. It interacts efficiently and very easily on a native device. It is supported by Google.
Flutter automated testing empowers you to meet high responsiveness in your application as it helps in discovering bugs and various issues in your application. A flutter is a tool for developing mobile, desktop, web applications with code & is a free and open-source tool.
Hello friends In this blog, we will learn about How to integrate flutter into the existing android app?. In this, we will see how we will integrate any Flutter app in Android. so let’s get started.

Add Flutter to existing Android App
Integrate Flutter To Existing App:
Flutter provides us with a platform to develop apps for Android and iOS. Using Flutter we can integrate modules of our Flutter project into any existing native projects. After integrating the Flutter project we can also develop the rest of the Flutter application and it will be automatically reflected in the parent projects.
Add Flutter to an existing Android app:
Flutter allows us to do a few things already integrated into Android apps which are explained below:
- This is a module build wizard that allows co-editing Android projects and Flutter projects in our Android Studio.
- It supports both types of apps like our Kotlin Java
- It can integrate and conform to the plugins in flutter and the flutter modules can be integrated seamlessly and as soon as we add the flutter SDK hooks in our Gradle file it auto builds the flutter modules we have created. and allows it to be important Flutter plugins can integrate and conform to the preexisting platform and how Flutter modules can then be seamlessly integrated as a result.
- Once we have integrated flutter you can also use flutter attach to the id so that we can connect to the app
Example of an existing application:
Following are the steps to integrate Flutter Project in Android Project.
Step 1:First of all we will open an android studio and for a new android project, we will select a new android studio project.
Step2:Now we can first create a screen from the android studio template with the help of the attached MVVM, name it whatever.
like you do in your android studio, select File>New>New project… and choose a template.
Step3:Now we see in the next step as soon as the android project is created a new android project opens now as soon as we run the project then a hello word written appears on the screen which is the default.
Step4:Now we will close and run our android project again before that we will create a project and select a flutter module in it in which we will set the project name and its SDK path, project location, etc.
Step5:When we create a new flutter project and run our project, some kind of output appears, which is shown in the image below.
Step6:Now we will open our android project again and right-click on our project, on right-click a dialog will open in this we will move the new section cursor and click on the module option.
Step7:As soon as we click on the module, create a new module comes, in this, we will select the option of import flutter module, in we will set the path of our flutter project and click on the finish button, which will import our flutter module.
Step8:The structure of our project changes as soon as the Flutter module is imported, we see that the Flutter project is also inbuilt in our Android project.
Now our native Android and Flutter Project is successfully integrated.
Implement:
Flutter provides FlutterActivity inside the android app that simulates the flutter experience.
We need to register flutter activity in AndroidManifest.xml.
<activity
android:name="io.flutter.embedding.android.FlutterActivity"
/>
dependencies {implementation project(':flutter')
}Code Implement:
You need to implement it in your code respectively:
First, we add Activity. Main. A button has been created in XML in which the name and id of the button have been given, which will help us to perform any action on the button. As below code is given in the reference.
<Button
android:id="@+id/button_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="OPEN FLUTTER PROJECT"
tools:ignore="MissingConstraints"
tools:layout_editor_absoluteX="127dp"
tools:layout_editor_absoluteY="417dp" />Next, we will define the android activity inside button in the main activity class which integrates the flutter project inside our android app it maintains its responsibilities like displaying the splash screen of android and flutter. As below code is given in the reference.
public class MainActivity extends AppCompatActivity {@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Button button=findViewById(R.id.button_id);
//startActivity(FlutterActivity.createDefaultIntent(this));
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(
FlutterActivity
.withNewEngine()
.initialRoute("/my_route")
.build(MainActivity.this)
);
}
});
}
