no_literal_bool_comparisons

Don't compare boolean expressions to boolean literals.

This rule is available as of Dart 3.0.

This rule has a quick fix available.

From Effective Dart:

DON'T use true or false in equality operations.

This lint applies only if the expression is of a non-nullable bool type.

BAD:

if (someBool == true) {
  print('true!');
}
while (someBool == false) {
  print('still false!');
}

GOOD:

if (someBool) {
  print('true!');
}
while (!someBool) {
  print('still false!');
}

To enable the no_literal_bool_comparisons rule, add no_literal_bool_comparisons under linter > rules in your analysis_options.yaml file:

linter:
  rules:
    - no_literal_bool_comparisons
