Ever thought about having only one instance per class across your entire app? Multiple instances can lead to a world of inconsistency or wasteful resource usage. Enter… The Singleton Design Pattern! Let's take this journey together and explore how it works with lazy, eager & factory variations Staying organized is key when building apps in Flutter - especially if you want to avoid issues like inconsistent behavior or wasted memory due to multiple instances of the same class. One solution for that? The Singleton Design Pattern! It helps ensure there's only one instance per class across your entire app, and we can use variations such as lazy initialization (only creating an object when it’s needed), eager instantiation (creating objects at startup) or factory constructor methods to do so. What are some of the ways you guys have used Singleton Pattern in Flutter? I'm curious about how others handle this situation and would love your thoughts on lazy, eager & other variations!
