sizeHint method
If possible give a hint of expected size of the encoding.
This method is used inside default implementation of encode
to avoid re-allocations.
Implementation
@override
int sizeHint(List<A> value) {
assertion(value.length == size, 'Invalid list length');
var byteSize = 0;
for (A element in value) {
byteSize += codec.sizeHint(element);
}
return byteSize;
}
