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

Question

我正在尝试构建我的flutter应用程序及其引发的编译错误，基于这个错误，它似乎是由flutter文件引起的，而不是我的代码。知道怎么解决这个问题吗？

PS C:UsersFlutterProjecttirthankar> flutter build web

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在2^62和-2^62-1之间有界，我知道你已经达到了64位机器中可以表示的int值的极限，但自从BigInt bi = BigInt.parse("9223372036854775807");开始以来，你有没有尝试过使用类BigInt
