decodeInt32 method
Use this when the value won't be larger than a normal int32. It's more efficient & cost less space.
Implementation
int decodeInt32(String key, {int defaultValue = 0}) {
final keyPtr = key.toNativeUtf8();
final ret = _decodeInt32(_handle, keyPtr, defaultValue);
calloc.free(keyPtr);
return ret;
}
