I upgraded a project to latest master and it's lit up like a xmas tree with 144 errors because null-safety seems to be enabled by default.
I'm working on a desktop app, and need Master, but am not ready to migrate to null safety yet. Is it possible to turn this off?
You can set the language version in the entrypoint, which might be lib/main.dart as a comment on the first line
// @dart=2.11
import 'package:flutter/material.dart';
void main() {
runApp(MyApp());
}
Null safety starts in 2.12, so using the version below that should avoid it.
No, we are not forced. Null safety is available in the Flutter beta channel. Some packages are fully null safety though. You can unsound null safety as well.
