Flutter17.Dismissible

ex:

import 'package:flutter/material.dart';

void main() => runApp(MaterialApp(
  home: HomePage(),
));

class HomePage extends StatelessWidget {
  final List<String> items = List.generate(20, (index) => 'item $index');

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: ListView.builder(
        itemCount: items.length,
        itemBuilder: (context, index) {
          final item = items[index];
          return Dismissible(
            onDismissed: (_) {
              items.removeAt(index);//删除条目
            },
            movementDuration: Duration(milliseconds: 100),
            key: Key(item),
            child: ListTile(
              title: Text('$item'),
            ),
            background: Container(color: Color(0xffff0000),),
          );
        },
      ),
    );
  }
}
