If you want to set the minimum character for the password of the Login and User-Sign-up, you need to open following file:

Project_HOME > lib > hooks_v2.dart

Look for the getMinimumPasswordLengthHook() method. By default, the minimum characters limit is set to 8. Replace it according to your requirement.

After modifications, restart the app and the changes will reflect on Maps.

@override
  MinimumPasswordLengthHook getMinimumPasswordLengthHook() {
    MinimumPasswordLengthHook minimumPasswordLengthHook = () {
      return 8;
    };
    return minimumPasswordLengthHook;
  }

Added in version 1.3.9
