I need help creating a Flutter e-commerce app with a fixed app bar and a dynamic content area for category displays, similar to Android fragments. I’m a beginner in Flutter.
Hey Charlie31, I was exploring something similar recently and I found that using a combination of a fixed AppBar along with a Scaffold’s body that changes content can work great for that kind of layout. One approach that worked for me was to use a State variable to keep track of which category content to show and then swap out widgets accordingly in the body. I was wondering though, have you thought about how you want to handle navigation between the scrolling content and the screens beneath the AppBar? In some cases, using something like a PageView or an IndexedStack can be super effective. It really depends on whether you want to maintain state between category switches or not. I’d love to hear what kind of user interactions you’re planning on implementing. How dynamic is your category layout going to be? Are you considering loading data from a server on the fly, or is it going to be static for now? Let’s chat more about this idea!
I have built similar Flutter apps and discovered that separating the fixed UI elements from variable content works well for managing state without device performance hit. In one case, I used a custom widget that wraps the dynamic category view, refreshed through state management without rebuilding the whole scaffold. This approach safeguarded the consistency of the app bar while allowing independent updates to category sections. Experimenting with different state management solutions helped me optimize for user experience, so I recommend testing both Provider and Bloc to see which integrates best with your project.
hey chrlie, try using an indexedstack to swapp content. it keeps state intact and lets u easily switch categories without losing data. hope this helps u out!
Hey Charlie31, I love seeing projects like this take shape! I was thinking that for dynamic category screens you might want to check out Flutter’s transition widgets like AnimatedSwitcher for some smooth effects when switching between categories, especially if you ever decide to load data asynchronously. Have you experimented with any of these or are you planning to stick to a more straightforward widget swap? I’m really curious about your approach on state management too; maybe you could try a more granular set-up where only the category content rebuilds while the rest of the page stays intact. What’s your plan for handling user interactions on category switches? It’d be cool to hear more about your design details. Cheers and happy coding!
