Customizing PopupMenuButton with Rounded Corners in Flutter

Flutter Development: Customizing PopupMenuButton with Rounded Corners

During your journey with Flutter development, you may encounter scenarios where the use of the PopupMenuButton widget is necessary. This widget is an excellent tool for presenting a popup menu to users, allowing them to select from a range of items. Although the PopupMenuButton comes with sharp corners by default, it's flexible enough to be customized with rounded corners if required.

Creating a Rounded PopupMenuButton: An Overview

To create a PopupMenuButton with rounded corners, you will need to utilize the 'shape' and 'borderRadius' properties. The 'shape' property should be assigned the RoundedRectangleBorder widget, and the 'borderRadius' property should be given a Radius.circular value according to the desired corner radius.

Example: Constructing a Rounded PopupMenuButton with a Corner Radius of 20

PopupMenuButton(
  child: Text("Show Popup Menu"),
  shape: RoundedRectangleBorder(
    borderRadius: BorderRadius.all(Radius.circular(20.0)),
  ),
)

Example: Designing a Rounded PopupMenuButton with a Corner Radius of 15

The following example demonstrates how to create a PopupMenuButton with a corner radius of 15. Additionally, the itemBuilder property is used to specify the items that appear in the popup menu.

PopupMenuButton(
  child: Text("Show Popup Menu"),
  shape: RoundedRectangleBorder(
    borderRadius: BorderRadius.all(Radius.circular(15.0)),
  ),
 itemBuilder: (context) => [
    PopupMenuItem(
      child: Text("pub.dev"),
    ),
    PopupMenuItem(
      child: Text("Flutter"),
    ),
    PopupMenuItem(
      child: Text("Google.com"),
    ),
    PopupMenuItem(
      child: Text("https://blogdeveloperspot.blogspot.com"),
    ),
 ],
)
