dart - dart 中整数的最大值是多少？

Question

我查遍了所有地方，但找不到与此主题相关的任何信息。另外，dart 中是否有类似 java 的 Long/BigDecimal 数据类型？

Answer 1

Dart 2

对于 dart2js 生成的 JavaScript Pixel Elephants，答案仍然是正确的。

within the range -2⁵³ to 2⁵³

其他执行平台具有 64 位的固定大小整数。

类型 BigInt 已添加到 typed_data

Since Dart 2.0 will switch to fixed-size integers, we also added a BigInt class to the typed_data library. Developers targeting dart2js can use this class as well. The BigInt class is not implementing num, and is completely independent of the num hierarchy.
