I have experienced this error and none of the above solution worked for me infact the option of clearing the flutter/bin/cache messed the entire vscode IDE. So I deleted the entire flutter SDK and installed fresh new SDK from flutter official website. After this installation everything was working fine.
回答2:
I had this issue after a flutter upgrade. Uninstalling the app from the device and then flutter running it again solved the problem.
回答3:
After deleting the flutter/bin/cache and running flutter clean, I couldn't get the dart sdk to load until I launched the flutter console (flutter_console.bat) that can be found in the directory where you installed flutter and ran flutter doctor there. That solved the problem.
回答4:
Do git clean -xffd in flutter installed directory(repo).
If it's a Flutter project first try flutter clean if did not work, try above git command.
If still not solved, delete everything inside /flutter/bin/cache and try.
If still not :D,
Do flutter channel master, flutter upgrade, and flutter clean. If nothing worked please add a comment below.
If you are in Dart environment out flutter/bin/cach/dart-sdk, you may be not upgraded dart-sdk. This happen to me Dart 2.5.0 with chololate installed. So I just did choco upgrade dart-sdk

"flutter upgrade"
you should upgrade your dart sdk
So try this command :
"choco install dart-sdk"
if this is not work for you download it from this link https://dart.dev/tools/sdk/archive; and replace it with your current dart-sdk in flutter
