flutter: parameter format not correct

Question

I am new to Flutter and today I've been stuck to one problem. I cannot debug my app because it says parameter format not correct

Parameter format not correct -

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:packageDebug'.
> Several variant outputs are configured to use the same file name "resources-debug.ap_", filters : MAIN:MAIN

Here's my flutter doctor

Doctor summary (to see all details, run flutter doctor -v):

I've looked for answers everywhere and they didn't work for my case. Most of the solutions are suggesting to change environment path. This is my path: C:\src\flutter\bin note: I'm using VSCode

Please help.. thank you!

Answer 1

This error occurred because of the app level Gradle.file minSdkVersion property is less than 20 or the targetSdkVersion property is less than 30.

It may work for you. In my case, it works perfectly.

minSdkVersion : 20

targetSdkVersion : 30
