Any advice?

[zubairehman]

Try upgrading flutter, make sure you are using v1.12 and dart 2.7

Let me know if issue still persists.

[engmsaleh]

I'm already using: Flutter 1.12.13+hotfix.5 Dart SDK 2.7

[zubairehman]

I just cloned the project and its working perfectly fine for me. Please make sure you followed the steps mentioned here to clone and build the project: https://github.com/zubairehman/flutter-boilerplate-project#how-to-use

[engmsaleh]

@zubairehman It worked, it was my fault thanks a lot

[zubairehman]

Glad to hear it worked :)
