Ep.2 - Abstract Factory | Flutter Design Patterns

This is the second episode of Design Patterns Series in Flutter, designed for beginners. In this episode, we are going to understand what Abstract Factory Pattern is. We will go through an overly complicated definition, understand it using analogy, continue with the flutter example from first episode and then understand when and why to use this design pattern along with the disadvantages it brings.

Wouldn't it be better to give the color as a variable instead of a method?



abstract class PlatformIndicator {
final Color color;
Widget build();
const
}

class AndroidIndicator implements PlatformIndicator {
@override
Color get color => Colors.red;



@override
Widget build() {
return color);
}
}

class IOSIndicator implements PlatformIndicator {
@override
Widget build() {
return color);
}

@override
Color get color => Colors.grey;
}
