Could not find an option named "no-sound-null-safety"

Question

I have this error when I try to debbug my app, I used to debbug my app with no sound null safety, I update flutter and it doesnt work now, how can I resolve it?

Answer 1

Had this issue, I couldn't even run a new project built with Flutter 3.10 itself.

I use VSCode so all I had to do, is to the settings and search for Additional, check you'll find this.

and also had to go into settings.json and remove another flag related to null safety,

Now I can build with no problem!
