UseResult.unless constructor
Initialize a newly created instance to annotate a function or method that
identifies a parameter parameterDefined that when present signals that
the result is used by the annotated member and does not need to be further
checked. For values that need to be used unconditionally, use the unnamed
UseResult
constructor, or if no reason is specified, the useResult
constant.
Tools, such as the analyzer, can provide feedback if
- a parameter named by parameterDefined is not declared by the annotated method or function.
Implementation
const UseResult.unless({required this.parameterDefined, this.reason = ''});
