popup alert in flutter

To display a popup alert in Flutter, you can use the showDialog function along with the AlertDialog widget. Here's an example of how you can create a simple popup alert:

  context: context,
  builder: (BuildContext context) {
    return AlertDialog(
      title: Text('Alert'),
      content: Text('This is a popup alert.'),
      actions: [
          child: Text('OK'),
          onPressed: () {

In the above code, showDialog is called to show the alert. The builder parameter is a callback that builds the dialog content. Inside the builder callback, an AlertDialog widget is returned. The AlertDialog widget consists of a title, content, and actions. In this example, the title is set to 'Alert' and the content is set to 'This is a popup alert'. The actions parameter is used to define the buttons in the alert dialog. In this case, a single TextButton is added with the label 'OK'. When the 'OK' button is pressed, the Navigator.of(context).pop() function is called to close the dialog.

You can customize the appearance and behavior of the popup alert by modifying the properties of the AlertDialog widget. For example, you can change the button labels, add additional buttons, or include other widgets in the content area.
