nextUint32 method Null safety
Extracts a big-endian 32-bit unsigned integer from the range.
Returns the value represented by the first four bytes of the range and removes those four bytes from the range.
Throws a BadEncoding if there are insufficient bytes in the range.
Implementation
int nextUint32() {
if (end < begin + 4) {
// Less than 4 bytes left: not enough for a 32-bit value
throw KeyBad('data incomplete');
}
final a = Uint8List.fromList(
[bytes[begin + 3], bytes[begin + 2], bytes[begin + 1], bytes[begin]]);
final value = a.buffer.asUint32List().first;
begin += 4;
return value;
