I upgraded Flutter today to version v1.12.13 but when I run the app, I get the following error -

I am using the latest version of CachedNetworkImageProvider.
This currently looks like an active issue. Changing the version to 2.0.0-rc fixes the error for time being.
As mentioned in the official page
Breaking change with ImageProvider.load in Flutter 1.10
The Flutter team made a breaking change with the ImageProvider in Flutter 1.10.15 (currently Master channel only).
If you are experiencing one of the following errors upgrade to 2.0.0-rc.
switch to cached_network_image: ^2.0.0-rc
If the issue still persists then try flutter clean and run.

The main problem is described here:

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.
The app was working fine but suddenlly its start showing the error when try to run or build

I believe there may be other ways to solve it, but I solved it by updating flutter with flutter upgrade
I'm having this problem, and ran out of options,

Basically the awesome notifications is trying to access "DecoderBufferCallback" variable from the flutter library but sadly in the flutter library they changed that variable name to "DecoderCallback"...
SO you need to actually edit the variable name in the library code of AwesomeNotifications from "DecoderBufferCallback" to "DecoderCallback".. This is their job but we are doing it for them
P.S.: I know the awesoome notifications version is older in this screenshot but i just wanted to show where to do the edit... so i opened up an older project
when i run my codes it gives this error

############## Solution Things ###############
That situation is caused by selecting wrong package version....
so, i try to change version of "flutter_form_builder"!
and i solved this problem!
This is due to incompatibilty of flutter_form_builder with your version of flutter. As advised on the github page of flutter_form_builder, you need to choose the plugin according to your version of flutter.
From the github page:
For Flutter 1.17.x, use version 3.12.x
For Flutter 1.20.x, use version 3.13.x
For Flutter 1.22.X, use version 3.14.x
You have to type the correct version number in pubspec.yaml
Remove pubspec.lock, remove podfile.lock, and run
cd ios && pod repo update && cd .. && flutter clean && flutter pub get
