Flutter doctor did not show any issues. What could be wrong?

executing: flutter run -d linux

Shows the following:

CMake Error at /snap/flutter/81/usr/share/cmake-3.10/Modules/CMakeTestCXXCompiler.cmake:45 (message): The C++ compiler

"/snap/flutter/current/usr/bin/clang++"

is not able to compile a simple test program.

It fails with the following output:

In Linux Mint 20.2 Cinnamon with Flutter 2.5.2 and snap 2.51.7 I fixed by doing

sudo apt-get install clang cmake ninja-build pkg-config libgtk-3-dev
flutter clean
flutter run -d linux

There is an issue with snap version of Flutter (https://snapcraft.io/flutter) April 15th 2021 release.

The solution is to do a manual install (https://flutter.dev/docs/get-started/install/linux#install-flutter-manually)
