IndexError class

A specialized RangeError used when an index is not in the range 0..indexable.length-1.

Also contains the indexable object, its length at the time of the error, and the invalid index itself.

IndexError(int invalidValue, dynamic indexable, [String? name, String? message, int? length]): Creates a new IndexError stating that invalidValue is not a valid index into indexable.
IndexError.withLength(int invalidValue, int length, {Object? indexable, String? name, String? message}): Creates a new IndexError stating that invalidValue is not a valid index into indexable.

end → int read-onlyoverride: The maximum value that value is allowed to assume.
hashCode → int read-onlyinherited: The hash code for this object.
indexable → Object? final: The indexable object that invalidValue was not a valid index into.
invalidValue → int read-onlyoverride: The invalid value.
length → int final: The length of indexable at the time of the error.
message → dynamic finalinherited: Message describing the problem.
name → String? finalinherited: Name of the invalid argument, if available.
runtimeType → Type read-onlyinherited: A representation of the runtime type of the object.
stackTrace → StackTrace? read-onlyinherited: The stack trace at the point where this error was first thrown.
start → int read-onlyoverride: The minimum value that value is allowed to assume.

noSuchMethod(Invocation invocation) → dynamic inherited: Invoked when a non-existent method or property is accessed.
toString() → String inherited: A string representation of this object.

check(int index, int length, {Object? indexable, String? name, String? message}) → int: Check that index is a valid index into an indexable object.
