Flutter error on building files in Android Studio

Question

I have newly installed Flutter on Android Studio. I had a source code of flutter which I want to open using it. I installed the latest flutter plugin and flutter SDK. But when I try to run the app, it shows me the following error:

Compiler message:
/C:/Flutter%20SDK/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_svg-0.14.4/lib/src/picture_stream.dart:92:3: Error: The superclass, 'Diagnosticable', has no unnamed constructor that takes no arguments.
  PictureStream();
  ^^^^^^^^^^^^^

I am completely new to this and have no idea where this error is pointing. I have the latest Flutter SDK version: Flutter 1.17.0 and Dart 2.8.1, it's a stable version. My Android Studio version is 3.6.2

Solution

Try executing this in your terminal :

flutter pub cache repair

If it doesn't work, deleting the flutter folder, along with the cache folder should do the job.

terminal error : 'flutter' is not recognized as an internal or external command, operable program or batch file.
