Here is my place-holder (non-optimal) implementation in my other package:
extension on Int32 {
Int32 replaceBitRange(int left, int right, int bits) {
final length = left - right + 1;
var value = this.value;
for (var i = 0; i < length; i++) {
final index = left - i;
if (bits.isSet(length - i)) {
value = value.setBit(index);
} else {
value = value.clearBit(index);
}
}
return Int32(value);
}
}
from binary.dart.
