RangeError.index constructor
Creates a new RangeError stating that index
is not a valid index
into indexable
.
An optional name
can specify the argument name that has the
invalid value, and the message
can override the default error
description.
The length
is the length of indexable
at the time of the error.
If length
is omitted, it defaults to indexable.length
.
Implementation
factory RangeError.index(int index, dynamic indexable,
[String name, String message, int length]) = IndexError;
