I want to upgrade my flutter to get new features such as null safety, but I didn’t want my previous project to affect them. I want new changes only for my new flutter project, I want to run my old project similar to the old way. Is there any way? Please guide me through it.
The above answer wasn’t working for me after I upgraded to
Dart v2.12 on the
beta channel. So I found these options:
You can add this to the top of any dart file to disable null-safety checks.
or similar to the answer above, I had to include a version prior to 2.12 to disable null safety. You would edit this line in the
environment: sdk: ">=2.11.0 <3.0.0"
