Avoid non null assertion check?

[coladarci]

Hello, all! I'm very new to the flutter / dart world but I'm a big fan.

In my early days of this journey I'm starting to feel that using the "trust me" ! operator can be abused by lazy engineers and goes against the entire reason for null safety in the first place. I'm sure there are times when it can't be avoided (?) but in those cases, I'd rather write an ignore: to the line to call it out.

I've researched this and found https://dcm.dev/docs/rules/common/avoid-non-null-assertion/ but couldn't find any linter in core dart/flutter linter that can do this. Am I missing something?

Thanks all for the great community!

I'd also like to see a lint like this, but before it can be added to package:lints, the linter will need to add support for it.

I'll close this issue in favor of dart-lang/linter#3008 which proposes adding a similar lint. If you have anything to add, feel free to respond there. The CL(PR) https://dart-review.googlesource.com/c/sdk/+/337140 also has a proposal implementation.

Thanks for considering this :D
