RangeError.range constructor - RangeError - dart:core library (original) (raw)

RangeError.range(

1. num invalidValue,
2. int? minValue,
3. int? maxValue, [
4. String? name,
5. String? message, ])

Create a new RangeError for a value being outside the valid range.

The allowed range is from minValue to maxValue, inclusive. If minValue or maxValue are null, the range is infinite in that direction.

For a range from 0 to the length of something, end exclusive, useRangeError.index.

An optional name can specify the argument name that has the invalid value, and the message can override the default error description.

Implementation

@pragma("vm:entry-point")
RangeError.range(
  num invalidValue,
  int? minValue,
  int? maxValue, [
  String? name,
  String? message,
]) : start = minValue,
     end = maxValue,
     super.value(invalidValue, name, message ?? "Invalid value");
