Hey guys, I’m new to Flutter and working on an e-commerce app. I’m trying to figure out how to show different category screens one after another, kind of like Android fragments.
I’ve got my home screen set up with a Scaffold, including an app bar and a drawer. What I need is to keep the app bar fixed and only change the body content dynamically based on the category data.
I’ve already created screens for different category levels (main categories, subcategories, etc.). Now I just need to learn how to swap these screens in and out of the home screen’s body.
My category structure goes something like this: main category > subcategory > sub-subcategory > super category.
Any tips on how to achieve this in Flutter? I’m just starting out, so any help would be awesome. Thanks!
hey Sky_Dreamer, I’ve been tinkering with flutter lately and found a cool way to handle multiple screens. try using a nested Navigator within ur main Scaffold. this lets u swap out the body content while keeping the app bar fixed.
for ur complex category structure, maybe look into using routes? u can define named routes for each category level and use Navigator.pushNamed() to move between em.
hows the project going so far? any other challenges ur facing?
In my experience, handling multiple category screens in Flutter becomes more manageable when using a dynamic Navigator approach. I developed a flexible category screen that loads the current category’s data and, upon tapping an item, pushes a new screen for the subcategory. This approach ensures that the app bar remains constant while only the body content changes. Additionally, integrating a state management solution such as Provider keeps the UI updated seamlessly, making the navigation process both efficient and scalable.
Hey Sky_Dreamer! I’m working on something similar and I’ve been wondering about the best way to handle multiple category screens too. Have you thought about using a nested navigation approach? It could be a neat way to keep your app bar fixed while swapping out the body content.
What if you set up a main Navigator for your overall app structure, then use a nested Navigator for your category screens? That way, you could push and pop category screens without affecting the main app layout.
I’m curious, how are you handling state management for your categories? Are you using something like Provider or Riverpod? It might make it easier to keep track of which category is selected across different screens.
Also, for your super detailed category structure, have you considered using a breadcrumb-style navigation? It could help users keep track of where they are in the category hierarchy.
This is such an interesting project! I’d love to hear more about how you’re tackling it. What’s been the trickiest part so far?
