Failed on Linux

Code works on web, I just added these desktop packages and first run on Linux...

Strangely I had reported the same issue to another repo in 2019. I got a new computer since then...

Solutions are here: https://github.com/webview/webview/issues/230

Put this in your docs:

Debian: sudo apt install libwebkit2gtk-4.0-dev

Now I'm getting this: Launching lib/main.dart on Linux in debug mode... lib/main.dart:1 CMake Error at cmake_install.cmake:61 (file): file INSTALL cannot copy file "/home/steve/Documents/GitHub/dfc/dashboard/build/linux/x64/debug/intermediates_do_not_run/dashboard" to "/usr/local/dashboard".

strangely, flutter clean (twice) fixed that last problem. Now another:
