13 hours ago Summary: The Dart Debug Adapter (DAP) fails to pause threads when starting a Flutter app in the new 3.24 version. The DAP sometimes stops at random locations in the framework code or shows an error indicating that Thread 1 is not paused.
a-siva
With new 3.24 flutter version DAP shows error when starting an app. No breakpoints are set manually, but it tries to stop. Sometimes it stops at some random spot in framework code, sometimes it shows error "Thread 1 is not paused".
There is related issue registered in https://github.com/nvim-flutter/flutter-tools.nvim/issues/402 which may provide additional details.
Client: neovim
Code to reproduce: for me the problem occurs in every repository, I tested with this one: https://github.com/sidlatau/flutter_email_sender/tree/master/example
