插件介绍

基于插件公开信息、社区数据与项目使用情况整理的选型参考。

flutter_tags 是一个 Flutter 包,可简化可选择和基于输入的标签创建,同时支持预定义标签和用户输入的标签。它提供直观的界面,并内置添加、删除和选择标签的功能,非常适合表单、筛选或标签系统。该包与 TextField 无缝集成,支持动态输入,并可通过样式和回调进行自定义。它轻量且易于使用,无需复杂的设置。

适合场景

  • 带有标签选择的表单输入
  • 用户生成内容标记
  • 使用动态标签过滤接口
  • 基于标签的搜索功能
  • 带有实时反馈的交互式表单元素

主要特点

  • 可选择且可编辑的标签
  • 内置 TextField 集成
  • 可自定义的外观和行为
  • 轻松添加/移除标签操作
  • 支持预定义和动态标签

适合对象

  • 开发交互式表单的开发者
  • 需要基于标签过滤的应用
  • 需要动态标签管理的UI组件
  • 专注于简洁、极简标签界面的项目
  • 快速原型设计标签密集型功能

使用建议

  • 有限的平台特定自定义
  • 输入标签没有内置验证
  • 可能需要额外的样式来适应复杂布局
  • 未针对非常大的标签列表进行优化
  • 依赖外部依赖项以实现高级功能

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);
          });
        },
      ),
      itemCount: _items.length, // required
      itemBuilder: (int index){          
            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
                  title: item.title,

                  textStyle: TextStyle( fontSize: _fontSize, ),
                  combine: ItemTagsCombine.withTextBefore,
                  image: ItemTagsImage(
                    image: AssetImage("img.jpg") // OR NetworkImage("https://...image.png")
                  ), // OR null,
                  icon: ItemTagsIcon(
                    icon: Icons.add,
                  ), // OR null,
                  removeButton: ItemTagsRemoveButton(
                    onRemoved: (){
                        // Remove the item from the data source.
                        setState(() {
                            // required
                            _items.removeAt(index);
                        });
                        //required

                    },
                  ), // OR null,
                  onPressed: (item) => print(item),
                  onLongPressed: (item) => print(item),
            );
    
      },
    );    
}

final GlobalKey<TagsState> _tagStateKey = GlobalKey<TagsState>();
// Allows you to get a list of all the ItemTags
_getAllItem(){
    List<Item> lst = _tagStateKey.currentState?.getAllItem;
    if(lst!=null)
        lst.where((a) => a.active==true).forEach( ( a) => print(a.title));        
}
