avoid_js_rounded_ints

Avoid JavaScript rounded ints.

此规则自 Dart 2.0 版本起可用。

AVOID integer literals that cannot be represented exactly when compiled to JavaScript.

When a program is compiled to JavaScript int and double become JavaScript Numbers. Too large integers (value < Number.MIN_SAFE_INTEGER or value > Number.MAX_SAFE_INTEGER) may be rounded to the closest Number value.

For instance 1000000000000000001 cannot be represented exactly as a JavaScript Number, so 1000000000000000000 will be used instead.

BAD:

int value = 9007199254740995;

GOOD:

BigInt value = BigInt.parse('9007199254740995');

要启用 avoid_js_rounded_ints 规则，请在你的 analysis_options.yaml 文件中，在 linter > rules 下添加 avoid_js_rounded_ints ：

linter:
  rules:
    - avoid_js_rounded_ints
