实现效果
实现
1.先在pubspec.yaml文件汇总引入fluttertoast的包：
fluttertoast: ^8.0.8 # 弹窗
2.封装弹框工具类DialogUtils:
import 'package:flutter/material.dart';
import 'package:fluttertoast/fluttertoast.dart';
/// @author longzipeng
/// @创建时间：2022/2/24
/// 封装自定义弹框
class DialogUtils {
/// 基础弹框
static alert(
BuildContext context, {
String title = "提示",
String content = "",
GestureTapCallback? confirm,
GestureTapCallback? cancle,
List<Widget>? actions, // 自定义按钮
}) {
showDialog(
context: context,
builder: (context) {
return AlertDialog(
title: Text(
'提示',
style: TextStyle(color: Theme.of(context).primaryColor),
),
content: Text(content),
actions: actions ??
<Widget>[
InkWell(
onTap: () {
if (cancle != null) {
cancle();
}
Navigator.of(context).pop();
},
child: const Padding(
padding: EdgeInsets.only(right: 20),
child: Text(
"取消",
style: TextStyle(color: Colors.grey),
),
),
),
InkWell(
onTap: () {
if (confirm != null) {
confirm();
}
Navigator.of(context).pop();
},
child: Padding(
padding: const EdgeInsets.only(right: 10),
child: Text(
"确定",
style: TextStyle(color: Theme.of(context).primaryColor),
),
),
)
],
);
});
}
/// 弹出关于界面
static alertAboutDialog(BuildContext context) {
showAboutDialog(
context: context,
applicationIcon: FlutterLogo(),
applicationName: 'flutterdemo',
applicationVersion: '1.0.0',
applicationLegalese: 'copyright 编程小龙',
children: <Widget>[
Container(
height: 70,
child: const Text(
"总而言之，言而总之，时而不知，终究自知",
maxLines: 2,
style: TextStyle(),
),
),
],
);
}
/// 显示普通消息
static showMessage(String msg,
{toastLength: Toast.LENGTH_SHORT,
gravity: ToastGravity.CENTER,
timeInSecForIosWeb: 1,
backgroundColor: Colors.grey,
fontSize: 16.0}) {
// 先关闭弹框再显示对应弹框
Fluttertoast.cancel();
Fluttertoast.showToast(
msg: msg,
toastLength: toastLength,
gravity: gravity,
timeInSecForIosWeb: timeInSecForIosWeb,
backgroundColor: backgroundColor,
fontSize: fontSize);
}
/// 显示错误消息
static showErrorMessage(String msg,
{toastLength: Toast.LENGTH_SHORT,
gravity: ToastGravity.CENTER,
timeInSecForIosWeb: 1,
backgroundColor: Colors.red,
fontSize: 16.0}) {
showMessage(msg,
toastLength: toastLength,
gravity: gravity,
timeInSecForIosWeb: timeInSecForIosWeb,
backgroundColor: backgroundColor,
fontSize: fontSize);
}
/// 显示警告信息
static showWaringMessage(String msg,
{toastLength: Toast.LENGTH_SHORT,
gravity: ToastGravity.CENTER,
timeInSecForIosWeb: 1,
backgroundColor: Colors.orangeAccent,
fontSize: 16.0}) {
showMessage(msg,
toastLength: toastLength,
gravity: gravity,
timeInSecForIosWeb: timeInSecForIosWeb,
backgroundColor: backgroundColor,
fontSize: fontSize);
}
/// 显示成功消息
static showSuccessMessage(String msg,
{toastLength: Toast.LENGTH_SHORT,
gravity: ToastGravity.CENTER,
timeInSecForIosWeb: 1,
backgroundColor: Colors.greenAccent,
fontSize: 16.0}) {
showMessage(msg,
toastLength: toastLength,
gravity: gravity,
timeInSecForIosWeb: timeInSecForIosWeb,
backgroundColor: backgroundColor,
fontSize: fontSize);
}
}测试
注意：这里ListTitleWidget是自己封装的组件，直接改为ListTitle就不会报错了
