Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

flutter_tags is a Flutter package that simplifies the creation of selectable and input-based tags, combining functionality for both pre-defined and user-entered tags. It provides an intuitive interface with built-in support for adding, removing, and selecting tags, making it ideal for forms, filters, or tagging systems. The package integrates seamlessly with TextField for dynamic input and supports customization through styling and callbacks. It's lightweight and designed for ease of use without requiring complex setup.

Use cases

  • Form inputs with tag selection
  • User-generated content tagging
  • Filtering interfaces with dynamic tags
  • Tag-based search functionality
  • Interactive form elements with real-time feedback

Key features

  • Selectable and editable tags
  • Built-in TextField integration
  • Customizable appearance and behavior
  • Easy add/remove tag operations
  • Supports both predefined and dynamic tags

Suitable for

  • Developers building interactive forms
  • Apps requiring tag-based filtering
  • UI components needing dynamic tag management
  • Projects focused on clean, minimal tag interfaces
  • Rapid prototyping of tag-heavy features

Considerations

  • Limited platform-specific customization
  • No built-in validation for input tags
  • May require additional styling for complex layouts
  • Not optimized for very large tag lists
  • Depends on external dependencies for advanced features

Simple usage


import 'package:flutter_tags/flutter_tags.dart';
.
.
.
List _items;
double _fontSize = 14;

@override
void initState(){
    super.initState();
    // if you store data on a local database (sqflite), then you could do something like this
    Model().getItems().then((items){
            _items = items;
        });
}

@override
Widget build(BuildContext context) {
    return Tags(
      key:_tagStateKey,
      textField: TagsTextField(
        textStyle: TextStyle(fontSize: _fontSize),
        constraintSuggestion: true, suggestions: [],
        //width: double.infinity, padding: EdgeInsets.symmetric(horizontal: 10),
        onSubmitted: (String str) {
          // Add item to the data source.
          setState(() {
              // required
            _items.add(str);
          });

            final item = _items[index];
    
            return ItemTags(
                  // Each ItemTags must contain a Key. Keys allow Flutter to
                  // uniquely identify widgets.
                  key: Key(index.toString()),
                  index: index, // required

                        setState(() {
                            // required
                            _items.removeAt(index);

      },
    );    
}

final GlobalKey<TagsState> _tagStateKey = GlobalKey<TagsState>();
