How to Make a Blog App with Flutter

Category & Tag Filters

class BlogFilterBar extends StatefulWidget {
  final List categories;
  final ValueChanged onCategoryChanged;
  const BlogFilterBar({super.key, required this.categories, required this.onCategoryChanged});
  @override State createState() => _BlogFilterBarState();
}

class _BlogFilterBarState extends State {
  String _selected = 'All';

  @override
  Widget build(BuildContext context) {
    return SingleChildScrollView(
      scrollDirection: Axis.horizontal,
      padding: const EdgeInsets.symmetric(horizontal: 16, vertical: 8),
      child: Row(
        children: ['All', ...widget.categories].map((cat) =>
          Padding(
            padding: const EdgeInsets.only(right: 8),
            child: FilterChip(
              label: Text(cat),
              selected: _selected == cat,
              onSelected: (sel) {
                setState(() => _selected = cat);
                widget.onCategoryChanged(cat);
              },
            ),
          ),
        ).toList(),
      ),
    );
  }
}

Search

class BlogSearch extends StatefulWidget {
  final void Function(String query) onSearch;
  const BlogSearch({super.key, required this.onSearch});
  @override State createState() => _BlogSearchState();
}

class _BlogSearchState extends State {
  final _ctrl = TextEditingController();

  @override
  void initState() {
    super.initState();
    _ctrl.addListener(() {
      // Debounce 300ms
      Future.delayed(const Duration(milliseconds: 300), () {
        widget.onSearch(_ctrl.text);
      });
    });
  }

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.all(16),
      child: TextField(
        controller: _ctrl,
        decoration: InputDecoration(
          prefixIcon: const Icon(Icons.search),
          hintText: 'Search articles...',
          border: OutlineInputBorder(borderRadius: BorderRadius.circular(12)),
        ),
      ),
    );
  }
}

UI & UX Suggestions

Use a white/light grey, blue primary, serif font for article body colour palette to match the app's purpose. Keep the navigation simple — a bottom nav bar or a single-scroll layout works best for this type of app. Make sure every interaction provides haptic or visual feedback so the app feels responsive and polished.
