Wrong generator result for empty classes #1081
Description
Steps to Reproduce
Create an empty class with the HiveType annotation.
@HiveType(typeId: 0)
class EmptyClass {}
Start the generator. The result is:
class EmptyClassAdapter extends TypeAdapter<EmptyClass> {
@override
final int typeId = 58;
@override
EmptyClass read(BinaryReader reader) {
return EmptyClass();
}
@override
void write(BinaryWriter writer, EmptyClass obj) {
writer.writeByte(0);
}
@override
int get hashCode => typeId.hashCode;
@override
bool operator ==(Object other) =>
identical(this, other) ||
other is EmptyClassAdapter &&
runtimeType == other.runtimeType &&
typeId == other.typeId;
}
But the correct result should be:
class EmptyClassAdapter extends TypeAdapter<EmptyClass> {
@override
final int typeId = 58;
@override
EmptyClass read(BinaryReader reader) {
final numOfFields = reader.readByte();
final fields = <int, dynamic>{
for (int i = 0; i < numOfFields; i++) reader.readByte(): reader.read(),
};
return EmptyClass();
}
@override
void write(BinaryWriter writer, EmptyClass obj) {
writer.writeByte(0);
}
@override
int get hashCode => typeId.hashCode;
@override
bool operator ==(Object other) =>
identical(this, other) ||
other is EmptyClassAdapter &&
runtimeType == other.runtimeType &&
typeId == other.typeId;
}
