I have suddenly run into an error when debugging, it was just working and this error popped up when I tried loading a new screen in main.dart.

BUILD FAILED in 18s


The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app.


Gradle task assembleDebug failed with exit code 1 Exited (sigterm)

Copying my own answer from similar SO question (Android version no longer working after upgrading flutter packages)

I saw similar errors a few days ago, and found out I needed to upgrade my project to support AndroidX.

I was able to migrate flutter project to support AndroidX without having to use Android studio.

Here's what I did:

  1. updated compileSdkVersion in build.gradle file to 28
  2. and android.useAndroidX=true and android.enableJetifier=true in gradle.properties

EDIT: If you see Unable to merge dex error, see This SO post that has upvoted solutions including (1) try clean and rebuild OR (2) add following in app/build.gradle file:

android {
    defaultConfig {
       multiDexEnabled true
    }
}

Hope this helps!
