Creating Beautiful Card UI in Flutter

In this tutorial, we will learn how to create beautiful and customizable card UI in Flutter. 

We will use the Card widget to create the card layout and other widgets like Image and Text to add images and text to the card. We will also learn how to customize the card's appearance by adding borders and changing its shape. 

By the end of this tutorial, you will have a good understanding of how to create beautiful and customizable card UI in Flutter.

A card is a sheet of Material used to represent some related information, for example an album, a geographical location, a meal, contact details, etc.

Eg1:

Card(
  // Define the shape of the card
  shape: RoundedRectangleBorder(
    borderRadius: BorderRadius.circular(4),
  ),
  // Define how the card's content should be clipped
  clipBehavior: Clip.antiAliasWithSaveLayer,
  // Define the child widget of the card
  child: Column(
    crossAxisAlignment: CrossAxisAlignment.start,
    children: <Widget>[
      // Add padding around the row widget
      Padding(
        padding: const EdgeInsets.all(15),
        child: Row(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: <Widget>[
            // Add an image widget to display an image
            Image.asset(
              ImgSample.get("reading.png"),
              height: 100,
              width: 100,
              fit: BoxFit.cover,
            ),
            // Add some spacing between the image and the text
            Container(width: 20),
            // Add an expanded widget to take up the remaining horizontal space
            Expanded(
              child: Column(
                crossAxisAlignment: CrossAxisAlignment.start,
                children: <Widget>[
                  // Add some spacing between the top of the card and the title
                  Container(height: 5),
                  // Add a title widget
                  Text(
                    "Cards Title 1",
                    style: MyTextSample.title(context)!.copyWith(
                      color: MyColorsSample.grey_80,
                    ),
                  ),
                  // Add some spacing between the title and the subtitle
                  Container(height: 5),
                  // Add a subtitle widget
                  Text(
                    "Sub title",
                    style: MyTextSample.body1(context)!.copyWith(
                      color: Colors.grey[500],
                    ),
                  ),
                  // Add some spacing between the subtitle and the text
                  Container(height: 10),
                  // Add a text widget to display some text
                  Text(
                    MyStringsSample.card_text,
                    maxLines: 2,
                    style: MyTextSample.subhead(context)!.copyWith(
                      color: Colors.grey[700],
                    ),
                  ),
                ],
              ),
            ),
          ],
        ),
      ),
    ],
  ),
),
