IndexError constructor Null safety

IndexError(
  1. int invalidValue,
  2. dynamic indexable,
  3. [String? name,
  4. String? message,
  5. int? length]
)

Creates a new IndexError stating that invalidValue is not a valid index into indexable.

The length is the length of indexable at the time of the error. If length is omitted, it defaults to indexable.length.

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

Implementation

IndexError(int invalidValue, dynamic indexable,
    [String? name, String? message, int? length])
    : this.indexable = indexable,
      this.length = length ?? indexable.length,
      super.value(invalidValue, name, message ?? "Index out of range");
