Dart / Flutter error: 'toStringDeep' isn't defined for the class 'Logger'


When I get this error, I use "flutter clean" and it solves the problem.


I ran into a similar issue, for me It only happens with Android Studio's interface run/debug button. It was working fine with flutter run command.

But clearing out the build files/cache fixed the issue.

1. Android Studio:

Menu Tool > Flutter > Flutter Clean

 

2. OR run the command on CLI:

flutter clean

 

3. Using shortcut

It doesn't have a default key shortcut to run flutter clean, but you can add one easily.
I added + H hotkey for flutter clean. You can define yours. Here is how:

  1. Open Preferences/Settings.

  1. Click on Keymap
  2. Search for flutter clean.
  3. Right click on Flutter Clean and select Add Keyboard shortcut

  1. Add the keyboard short cut you prefer. I added Command + H

Now you can do it quicker.


alternatively, just remove the build folder.
