IndexError.withLength constructor Null safety

  1. @Since("2.19")
IndexError.withLength(
  1. int invalidValue,
  2. int length,
  3. {Object? indexable,
  4. String? name,
  5. String? message}
)

The length is the length of indexable at the time of the error.

The message is used as part of the string representation of the error.

Implementation

@Since("2.19")
IndexError.withLength(int invalidValue, this.length,
    {this.indexable, String? name, String? message})
    : super.value(invalidValue, name, message ?? "Index out of range");
