Execution failed for task ':app:mergeDexDebug'. Firestore | Flutter

Question

Trying to use Firestore in my project. My project is a brand new one, but having problems running the app on my device without getting an error: Execution failed for tas

Answer 1

Fixed the issue, but don't understand why. Why do I need to enable multiDex when I believe Firestore is using AndroidX?

Anyway, the fix. Add multiDexEnabled true to your app/build.gradle

defaultConfig {
    // TODO: Specify your own unique Application ID 
    (https://developer.android.com/studio/build/application-id.html).
    applicationId "com.example.poll"
    minSdkVersion 16
    targetSdkVersion 28
    versionCode flutterVersionCode.toInteger()
    versionName flutterVersionName
    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    //This line here...
    multiDexEnabled true
}
