使用 Visual Studio 在 Flutter 上运行 Gradle 时出错

Question

i have been having this issue on flutter with Visual Studio Code during the debugging session for more than a week now, have tried all possible answers i saw but it's still now working and i need to run my app to see my progress.

if there's any alternative on how to run the app with please kindly provide just to run the app for now.

Am suppose to know if i'm going good or lacking behind my classes.

Launching lib\main.dart on TECNO Camon CX in debug mode...
