这么大个程序员摸鱼社区，竟然完全没有Flutter相关的技术内容，那么我就先随便发点东西打破0发帖吧！

这是个简易的dialog封装，使用方便，代码挺基础的。

使用方式

IWPZDialog.show(
      context,
      title: '提示',
      height: 300,
      cancelToDismiss: true,
      onCancelTap: () {
        print('点击了取消');
      },
      onOKTap: () async {
        print('点击了确定');
      },
      contentWidget: Container(
        child: Text('我是正文内容'),
      ),
    );

iwpz_dialog.dart

import './navigator_util.dart';

  static void show(
    BuildContext context, {
    String title = '', //标题
    String content = '', //正文，如果有contentWidget，则无视
    Widget? contentWidget, //正文widget
    bool showCancel = true, //是否显示取消
    bool tapToDismiss = true, //点击空白处关闭
    bool cancelToDismiss = true, //点击取消是否关闭
    double height = 220, //宽度
    double width = 400, //高度
    Function? onOKTap, //onOK
    Function? onCancelTap, //onCancel
  }) {
