How can I fix instance of 'class name' printed out Flutter

Question

I'm trying to print forecast.dart, but I'm getting 'instance of WeatherData' printed out. I added @override String toString() but no changes.. I'm not quite sure why forecast.dart is not printed out.. please help!

Answer 1

@override
String toString();

You need to actually add an implementation. return the string you want to see when it prints.

Answer 2

You need to implement toString. For example, you could do it like this:

@override
String toString() => 'Weather for ${placeName ?? 'unknown'}';

Alternatively, you could use https://pub.dev/packages/freezed. It automatically generates useful functions (such as fromJson, toJson, toString) for you. You'll save a lot of time this way.
