Linter rules not working

analysis_options.yaml:

linter:
  rules:
    - empty_statements
    - avoid_empty_else

example.dart:

void main(){
  if(1+2==3){}else{}
}

This shows no warnings or errors.

I did not test other rules but above rules are the ones that are not working.

Hello, I recommend testing other linter rules as well, to see all of them work as expected:

It seems they are working as intended and that is with if and else statements ending in semicolons to avoid confusion on which following statements will execute. You can see their intentions here:

https://github.com/dart-lang/linter/blob/master/lib/src/rules/empty_statements.dart#L21
https://github.com/dart-lang/linter/blob/master/lib/src/rules/avoid_empty_else.dart#L17

Possibly these can be expanded to your situations as they are dead code or new lints could be introduced(if they don't exist already).
