Constructors
- RangeError(dynamic message)
- Create a new RangeError with the given
message. - RangeError.index(int index, dynamic indexable, [String? name, String? message, int? length])
factory
- Creates a new RangeError stating that
index is not a valid index into indexable. - RangeError.range(num invalidValue, int? minValue, int? maxValue, [String? name, String? message])
- Create a new RangeError for a value being outside the valid range.
- RangeError.value(num value, [String? name, String? message])
- Create a new RangeError with a message for the given
value.

Static Methods
- checkNotNegative(int value, [String? name, String? message]) → int
- Check that an integer value is non-negative.
- checkValidIndex(int index, dynamic indexable, [String? name, int? length, String? message]) → int
- Check that
index is a valid index into an indexable object. - checkValidRange(int start, int? end, int length, [String? startName, String? endName, String? message]) → int
- Check that a range represents a slice of an indexable object.
- checkValueInInterval(int value, int minValue, int maxValue, [String? name, String? message]) → int
- Check that an integer
value lies in a specific interval.
