I tried installing flutter by following the steps at https://flutter.dev/docs/get-started/install , but kept running into the following error when inputting flutter in to Command Prompt:

Unhandled exception: FileSystemException: Cannot open file, path = 'C:\Users\matt\AppData\Roaming.flutter_tool_state' (OS Error: Access is denied. , errno = 5) #0 _File.throwIfError (dart:io/file_impl.dart:645:7) #1 _File.openSync (dart:io/file_impl.dart:489:5) #2 _File.writeAsBytesSync (dart:io/file_impl.dart:614:31) #3 _File.writeAsStringSync (dart:io/file_impl.dart:638:5) #4 ForwardingFile.writeAsStringSync (package:file/src/forwarding/forwarding_file.dart:154:16) #5 ErrorHandlingFile.writeAsStringSync.

(OS Error: Access is denied. , errno = 5)

Error 5: Access denied is a known issue on Windows 10. This error prevents you from installing software on your computer and accessing or modifying certain files.

The reason for this issue is the non-availability of the permissions. Windows 10 will prevent you from installing if you don’t have the Administrator privileges or if your account is not the administrator account.
