steps to get to this point:
- delete Podfile.lock
- run pod install
- flutter clean && flutter run --verbose
here is code for login.dart:
onTap: () async {
if (formKey.currentState!.validate()) {
formKey.currentState!.save();
bool value = await Provider.of<AuthService>(context,
listen: false)
.signIn();
if (value.toString() == "true") {
Navigator.of(context).pushNamedAndRemoveUntil(
homeRoute, (route) => true);
} else {
scaffoldKey.currentState?.ShowSnackBar(
const snackBar(content: Text('Connected')));
}
}
},
and it took 26min to run and give me this error. I have been trying to figure it out for nearly 2 days but nothing works! Any thoughts?
