Description:
adaptive number
adaptive_number #
A library providing a Number implementation that is dependent on the platform it is compiled for.
For JS runtimes, the implementation uses a 64-bit signed fixed-width integer, for all other platforms
the default Dart int data type.
Use cases of this library #
The Number substitute is useful in situations where a value may overflow on JS runtimes since the available value range
is not the same compared to mobile or desktop platforms:
https://api.dart.dev/stable/2.8.4/dart-core/int-class.html
The overflow on JS environments can be circumvented by using a BigInt or the fixed-with implementation of this library:
https://pub.dev/packages/fixnum
The disadvantage of just replacing all usages of int with BigInt or fixnum/Int64 is that the performance on
mobile platforms may suffer significantly.
The adpative_number library takes a conditional import approach to ease this problem:
If it runs on a JS runtime, Number wraps a fixnum/Int64
For all other platforms Number wraps a default Dart int type.
Usage #
A Number instance is created by wrapping it around a default int value:
import 'package:adaptive_number/adaptive_number.dart';
void main() {
final number1 = Number(93432);
final number2 = Number(42435);
assert((number1 + number2) == Number(51777));
}

All other operations on Number behave the same way as with int.
