Gradle Error when running flutter app

Hey! I just installed Flutter in VScode and I want to run the first demo app. But when I type “flutter run” I always recieve the same message: `FAILURE: Build failed with an exception.

  • Where:
    Script ‘C:\Users\jaspa\Desktop\Coding\App\flutter\packages\flutter_tools\gradle\flutter.gradle’ line: 991

  • What went wrong:
    Execution failed for task ‘:app:compileFlutterBuildDebug’.
    → Process ‘command ‘C:\Users\jaspa\Desktop\Coding\App\flutter\bin\flutter.bat’’ finished with non-zero exit value 1

  • Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

  • Get more help at https://help.gradle.org

BUILD FAILED in 12s
Running Gradle task ‘assembleDebug’…
Running Gradle task ‘assembleDebug’… Done 13,5s

Hope you can help me.
Thanks
