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(ChainType value) {
switch (value.runtimeType) {
case Development:
case Local:
case Live:
return 1;
case Custom:
return (value as Custom)._sizeHint();
default:
throw Exception(
'ChainType: Unsupported "$value" of type "${value.runtimeType}"');
}
}
