Flutter 编译错误 "The integer literal 9223372036854775807 can't be represented exactly in JavaScript"

Question

我正在尝试构建我的 flutter 应用程序并抛出编译错误，基于错误，它似乎是 flutter 文件而不是我的代码。知道如何解决这个问题吗？

PS C:\Users\FlutterProject\tirthankar> flutter build web
Target dart2js failed: Exception: /C:/Flutter/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_inappwebview-3.4.0+1/lib/src/X509Certificate/asn1_decoder.dart:163:25:

    int int64MaxValue = 9223372036854775807;
                        ^^^^^^^^^^^^^^^^^^^

下面是 dart/flutter 中失败的代码。

static List<int> loadSubContent({@required Iterator<int> iterator}) {
    var len = getContentLength(iterator: iterator);
    int int64MaxValue = 9223372036854775807;

    if (len >= BigInt.from(int64MaxValue)) {
      return <int>[];
    }

    var byteArray = <int>[];

    for (var i = 0; i < len.toInt(); i++) {
      if (iterator.moveNext()) {
        var n = iterator.current;
        if (n != null) {
          byteArray.add(n);
        }
      } else {
        throw ASN1OutOfBufferError();
      }
    }

    return byteArray;
  }

我相信 int 的范围在 2^62 和 -2^62-1 之间，我知道您已经达到了 64 位机器可以表示的 int 值的极限，但是您是否尝试过使用classBigInt从头开始BigInt bi = BigInt.parse("9223372036854775807");
