Answer 1

I encountered the issue building a Flutter application and I resolved it following the official guide: https://developer.android.com/studio/build/multidex

You simply have to:

0. (Android: Go to Refactor > Migrate to AndroidX
(If you are on a Flutter project, to migrate the module, you have to go to Tools > Flutter > Open for Editing in Android Studio

1. (Both) Modify the module-level build.gradle file to enable multidex and add the multidex library as a dependency, as shown here:

android {
    defaultConfig {
        ...
        minSdkVersion 15 
        targetSdkVersion 28
        multiDexEnabled true
    }
    ...
}

dependencies {
  implementation 'com.android.support:multidex:1.0.3'
}

2. (non-Flutter) If you do not override the Application class, edit your manifest file to set android:name in the tag as follows:

    
        ...
    

2. (Flutter) If you do not override the Application class, edit your manifest file to set android:name in the tag as follows:

    
        ...
    

3.(Flutter) Create a custom class under project/android/app/src/main/[java or kotlin folder]/[your/package/appName]
kotlin version: App.kt

package your.package.appName

import io.flutter.app.FlutterApplication
import android.content.Context
import androidx.multidex.MultiDex

class App : FlutterApplication() {

    override fun attachBaseContext(base: Context) {
        super.attachBaseContext(base)
        MultiDex.install(this)
    }

}

java version: App.java

package your.package.appName;

import io.flutter.app.FlutterApplication;
import android.content.Context;
import androidx.multidex.MultiDex;

public class App extends FlutterApplication {

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }

}

4. (Both) Celebrate if you did it!! :D
