Flutter App stuck at “Running Gradle task ‘assembleDebug’… “

When I run the app it get stuck

Launching lib\main.dart on Lenovo A319 in debug mode...
Running Gradle task 'assembleDebug'...
(This is taking an unexpectedly long time.)

It never initialize Gradle nor the dependencies

Solution to answer:

Here is solution in my case.

  1. Open your flutter Project directory.
  2. Change directory to android directory in your flutter project directory cd android
  3. clean gradle ./gradlew clean
  4. Build gradle ./gradlew build or you can combine both commands with just ./gradlew clean build (Thanks @daniel for the tip)
  5. Now run your flutter project. If you use vscode, press F5. First time gradle running assembleDebug will take time.

PS: Delete gradle in case of all that steps don't work
