void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({Key? key}) : super(key: key);

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  List<String> list = [];

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('插件 FlutterMultipleFill'),
        ),
        body: Center(
          child: Column(
            children: [
              const SizedBox(
                height: 10,
              ),
              FlutterMultipleFill(
                circleAvatarTextStyle: const TextStyle(fontSize: 12),
                circleAvatarColor: Colors.black,
                chipTextStyle:
                    const TextStyle(fontSize: 12, color: Colors.white),
                chipColor: Colors.blue,
                chipLabelPadding: 1,
                inputDecoration: const InputDecoration(
                  hintText: "添加邮箱",
                  filled: false,
                  hintStyle: TextStyle(fontSize: 12),
                ),
                emailPattern: true,
                boxDecoration: const BoxDecoration(color: Colors.transparent),
                boxPadding: 0,
                keyboardType: TextInputType.emailAddress,
                // 获取填写的所有值作为列表
                onfillCallback: (List<String> value) {
                  setState(() {
                    list = value;
                    print(list);
                  });

flutter_multiple_fill 是一个用于在 Flutter 应用中实现多字段填充的插件。它通常用于表单中，允许用户一次性填写多个字段，并且可以根据需要进行验证和提交。

安装

首先，你需要在 pubspec.yaml 文件中添加 flutter_multiple_fill 插件的依赖：

dependencies:
  flutter:
    sdk: flutter
  flutter_multiple_fill: ^1.0.0  # 请检查最新版本

然后运行 flutter pub get 来安装依赖。

基本用法

flutter_multiple_fill 插件提供了一个 MultipleFill 小部件，你可以通过它来创建多字段填充的表单。

import 'package:flutter/material.dart';
import 'package:flutter_multiple_fill/flutter_multiple_fill.dart';

class MyForm extends StatefulWidget {
  [@override](/user/override)
  _MyFormState createState() => _MyFormState();
}

class _MyFormState extends State<MyForm> {
  final _formKey = GlobalKey<FormState>();
  Map<String, String> _formData = {};

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Multiple Fill Example'),
      ),
      body: Padding(
        padding: const EdgeInsets.all(16.0),
        child: Form(
          key: _formKey,
          child: MultipleFill(
            fields: [
              FillField(
                id: 'name',
                label: 'Name',
                validator: (value) {
                  if (value == null || value.isEmpty) {
                    return 'Please enter your name';
                  }
                  return null;
                },
              ),
              FillField(
                id: 'email',
                label: 'Email',
                validator: (value) {
                  if (value == null || value.isEmpty) {
                    return 'Please enter your email';
                  }
                  if (!value.contains('@')) {
                    return 'Please enter a valid email address';
                  }
                  return null;
                },
              ),
              FillField(
                id: 'password',
                label: 'Password',
                obscureText: true,
                validator: (value) {
                  if (value == null || value.isEmpty) {
                    return 'Please enter your password';
                  }
                  if (value.length < 6) {
                    return 'Password must be at least 6 characters';
                  }
                  return null;
                },
              ),
            ],
            onChanged: (data) {
              setState(() {
                _formData = data;
              });
            },
          ),
        ),
      ),
      floatingActionButton: FloatingActionButton(
        onPressed: () {
          if (_formKey.currentState!.validate()) {
            // 表单验证通过，处理表单数据
            print(_formData);
          }
        },
        child: Icon(Icons.save),
      ),
    );
  }
}
