Lint for empty catch blocks

[zoechi]

This is a code smell and would be great if the linter could inform about it.

Would you want to treat the following equally?

try {
  ...
} catch(exception, stackTrace) {
  // ignore
}

vs.

try {
  ...
} catch(exception, stackTrace) { }

Maybe this is where linter-specific comments come into play:

try {
  ...
} catch(exception, stackTrace) {
  // dartlint:ignore:empty_catch
}

(Not a real comment format but you get the idea.)

I would require a linter comment to silent hints/warning like in your 3rd example
