toInt abstract method Null safety
Returns this BigInt as an int.
If the number does not fit, clamps to the max (or min) integer.
Warning: the clamping behaves differently between the web and native platforms due to the differences in integer precision.
var bigNumber = BigInt.parse('100000000000000000000000'); print(bigNumber.isValidInt); // false print(bigNumber.toInt()); // 9223372036854775807
