avoid_bool_literals_in_conditional_expressions

Avoid bool literals in conditional expressions.

AVOID bool literals in conditional expressions.

BAD:

condition ? true : boolExpression
condition ? false : boolExpression
condition ? boolExpression : true
condition ? boolExpression : false

GOOD:

condition || boolExpression
!condition && boolExpression
!condition || boolExpression
condition && boolExpression

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

linter:
  rules:
    - avoid_bool_literals_in_conditional_expressions

If you're instead using the YAML map syntax to configure linter rules, add avoid_bool_literals_in_conditional_expressions: true under linter > rules:

linter:
  rules:
    avoid_bool_literals_in_conditional_expressions: true
