Exception: [!] Your app is using an unsupported Gradle project

I am trying to run my existing flutter application and I am getting this exception. How can I solve this issue?

Exception: [!] Your app is using an unsupported Gradle project. To fix this problem, create a new project by running flutter create -t app <app-directory> and then move the dart code, assets and pubspec.yaml to the new project.

Here are my Flutter doctor results:

if anyone has this problem, just add the line id "dev.flutter.flutter-gradle-plugin" to plugin section in android/app/build.gradle

Anyone facing this issue. Do as it says.

Create a new Project and copy the build.gradle files contents into your old projects gradle file.

That's it. Don't forget to rename the projects package name.

You might have removed certain lines of code from

project/android/app/build.grade

add below below lines of code before

android {
    namespace "com.example.test_app"
    compileSdkVersion flutter.compileSdkVersion
    ndkVersion flutter.ndkVersion...

lines of code to be added:

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

For everyone landing here after making changes to the gradle for firebase or smth, it might seem stupid but check that the autoformat(if you have it enabled) didn't make funny things like putting spaces between "->" or "+=" turning them into "- >" or "+ ="

If you have the backup of your project than go to

project/android/app/build.grade copy all the code and paste it to your project app/build.grade file. Clean Project Now Enjoy. Your error will not appear.

Maybe you removed a line from the

project/android/app/build.grade

Try adding this Piece of Code

apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

after the line

apply plugin: 'com.android.application'
