Hello, this is Dr. Ho of Haiti. Today, we will look at three methods you can try when you cannot see the red line in the error message in Android Studio.


1. File > Power Save Mode  uncheck




2. file > invalidate Caches...



3. terminal > flutter clean > flutter pub get > flutter upgrade



If you cannot do the above three things, we recommend that you try creating the project again or reinstalling Android Studio. All of the above methods may not work.
