avoid-identical-exception-handling-blocks

added in: 1.9.0
warning

Warns when a try / catch has multiple catch blocks with the same body.

Consider adding additional information for each caught exception.

Example​

❌ Bad:

void main() {
  try {
    print('hello');
  } on StateError catch (error) {
    print(error);
  } on Exception catch (error) { // LINT
    print(error);
  }
}

✅ Good:

void main() {
  try {
    print('hello');
  } on StateError catch (error) {
    print('Got StateError $error');
  } on Exception catch (error) {
    print('Got Exception $error');
  }
}
