this error hapend when dupg my flutter app how can solve this problem
The main problem is described here:
/D:/program/flutter/flutter/packages/flutter/lib/src/widgets/framework.dart:4919:28: Context: 'StatefulElement.build' is defined here. Widget build() => state.,build(this);
I expect you have debugged your code and maybe accidentally put the comma in the framework.dart file.
Go to this specific file, double-check and remove the comma.
Fairly new to Flutter, decided to build for Web and got these following errors:

I tried upgrading packages, but no luck. Any idea what might be causing this issue?
I had lots of reference of '.r' through my flutter app and I replaced all '.r' references with '' empty string and I came to to know that dart files also have been modified and now I get these errors in my debug console. I tried to fix these but seems like re-adding '.r' isn't fixing these problems.
