Flutter error after development environment change

Question

I recently experienced a driver issue and while troubleshooting it I wiped my computer and reset my development environment, however I now get the following errors after trying to build my app on android.

C:\Users\cianr\AppData\Local\Pub\Cache\hosted\pub.dev\firebase_messaging-14.7.10\android\src\main\java\io\flutter\plugins\firebase\messaging\FlutterFirebaseMessagingPlugin.java:389: error: cannot find symbol
            .checkSelfPermission(Manifest.permission.POST_NOTIFICATIONS)
                                                    ^
  symbol:   variable POST_NOTIFICATIONS
  location: class permission
C:\Users\cianr\AppData\Local\Pub\Cache\hosted\pub.dev\firebase_messaging-14.7.10\android\src\main\java\io\flutter\plugins\firebase\messaging\FlutterFirebasePermissionManager.java:63: error: cannot find symbol
    permissions.add(Manifest.permission.POST_NOTIFICATIONS);
                                       ^
  symbol:   variable POST_NOTIFICATIONS
  location: class permission

After seeing this error I reverted back to a previous working branch via git and still got the same error, then i removed the firebase messaging plugin from my pubspec.yaml file and all the code that goes along with it, there after I got the following error message leading me to think its an issue with my environment.

I re-setup my environment in the following manner (windows)

1. setup git
2. downloaded android studio and the cli tools
3. downloaded vscode and enabled flutter and dart plugins
4. downloaded the flutter zip file and extracted it to C:src
5. added flutter to environment variables
6. downloaded jdk 17
7. added JAVA_HOME to both system and user variables

My flutter doctor:

How can i fix this?

Answer 1

Perhaps when you modified your setup, you also altered the Android version used for compilation, leading to changes in the process of permissions. Take a look at this Stack Overflow question, it might provide some useful insights : Can not find Symbol Manifest.permission.WRITE_EXTERNAL_STORAGE on v23

Answer 2

Update: Doing a clean install of windows solved the problem, must've had something to do with the old files that were kept on my computer causing problems.
