Gradle error: D8: Program type already present

[InMatrix]

I'm not sure what was changed, but I suddenly couldn't run my app on Android devices. I've already tried flutter clean. Please see the console output below. Thanks!

I solved it by deleting the android folder in my project and rerun flutter create.

I solved it by deleting the android folder in my project and rerun flutter create.

Its flutter create . Note the dot.

[ArthurAttout]

Re-creating the project with flutter-create didn't work for me. I have the sample app (that is automatically created when starting a project) only with the following dependencies added :

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2
  firebase_storage: 2.1.1+2
  image_picker: 0.6.0+2

[gokhanersoy]

I solved the problem by running following 2 commands:

1- flutter clean
2- flutter run

that's all.

The Gradle failure may have been because of AndroidX incompatibilities in this Flutter app.
See https://goo.gl/CP92wY for more information on the problem and how to fix it.

Gradle task assembleDebug failed with exit code 1

same type of error but any of above solutions didn't work for me..

[adolfdsilva]

In my case, I re-created the project to enable web-support. So I did
flutter create .

This ended up creating a java folder in my main package and thus creating the same

MainActivity.java class

But I was using kotlin and which already had a MainActivity class.
So rolled back my changes and did
flutter create -i swift -a kotlin .

Remember the flutter create template by default supports java, more info here

It didn't mess up my iOS though 🤔

Thank you, it's work for me

[jessndaa]

or

[ToemTheara]

Not easy.

[itzbernoulli]

for me, I had to

delete the kotlin files in the android/app/src/main directory
cd into the android directory
run ./gradlew clean

problem solved.

[zstima]

for some reason i had both java and kotlin dirs in my project (probably commited java and then later switch to kotlin and when i pulled i got both present in my project)

So for me, solution was to delete com/package/java dirs, so java code dir
