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(CustomMetadataV15 value) {
return BTreeMapCodec(
keyCodec: StrCodec.codec,
valueCodec: CustomMetadataV15Value.codec,
).sizeHint(value.map);
}
