⚡ Semantic Widget

The contents of the components inside the dialog are encapsulated by semantic functions in advance to quickly build the dialog, as shown in the following table

YYDialog YYAlertDialogWithDivider(BuildContext context) {
  return YYDialog().build(context)
    ..width = 220
    ..borderRadius = 4.0
    ..text(
      padding: EdgeInsets.all(25.0),
      alignment: Alignment.center,
      text: "确定要退出登录吗?",
      color: Colors.black,
      fontSize: 14.0,
      fontWeight: FontWeight.w500,
    )
    ..divider()
    ..doubleButton(
      padding: EdgeInsets.only(top: 10.0),
      gravity: Gravity.center,
      withDivider: true,
      text1: "取消",
      color1: Colors.redAccent,
      fontSize1: 14.0,
      fontWeight1: FontWeight.bold,
      onTap1: () {
        print("取消");
      },
      text2: "确定",
      color2: Colors.redAccent,
      fontSize2: 14.0,
      fontWeight2: FontWeight.bold,
      onTap2: () {
        print("确定");
      },
    )
    ..show();
}

⚡ Custom Widget

Customize dialog interior component content

  • Since the existing semantic components only assist in the rapid UI construction, they are far from meeting the requirements in actual project development
  • So it provides the ability to insert custom semantic components into dialog

Insert the component into the dialog through ‘widget()’

YYDialog YYDialogDemo(BuildContext context) {
  return YYDialog().build(context)
    ..width = 220
    ..height = 500
    ..widget(
      Padding(
        padding: EdgeInsets.all(0.0),
        child: Align(
          alignment: Alignment.centerLeft,
          child: Text(
            "",
            style: TextStyle(
              color: Colors.black,
              fontSize: 14.0,
              fontWeight: FontWeight.w100,
            ),
          ),
        ),
      ),
    )
    ..show();
}

⚡ Without the Context to invoke

  • Application scenario: after the network request comes back, there is no Context to refer to in the callback, at this time, the Context needs to be initialized in advance, and then the dialog can be called without the Context

1、init

Call static methods before show dialog YYDialog.init(context);

class AppHome extends StatelessWidget {
  Widget build(BuildContext context) {
    //1、init context
    YYDialog.init(context);
    //2、Subsequent use may not be required context
    ......
  }
}

2、use

direct use YYDialog,Note that it must be called build()

YYDialog YYAlertDialogBody() {
  return YYDialog().build()
    ..width = 240
    ..text(
      text: "Hello YYDialog",
      color: Colors.grey[700],
    )
    ..show();
}

🔥🔥 Attention

1、dismiss

  • Do not use ‘Navigator.pop(context)’ to make the popover disappear, or you will close your page
  • This problem has been solved internally in YYDialog, and you can simply call ‘dismiss()’ supplied internally
var yyDialog = YYDialog();
yyDialog?.dismiss();
