How To Easily Customize Flutter Card Height

In this post, we’ll learn what Flutter card height is and how to change/customize it.

We’ll explain it step by step with an easy but proper Flutter example code. First, we’ll see what the default Flutter card height is. After that, we’ll change it using practical examples.

After reading this post, you’ll be able to easily change Flutter card height in your own Flutter code as well.

So without any delay, let’s dive right into its implementation.

What is Flutter Card Height?

It specifies the vertical(top and bottom) size that the card widget covers. Let’s now understand it with practical examples.

Default Height of Flutter Card Widget

For that, we have to implement a simple Flutter card widget. The card widget has no specific height of its own. So we’ll pass a Flutter text widget to it. See below code:

Card(child: Text('Default Flutter Card Height'))

You can see in the above image that the card has no height of its own. It only adjust its height depending on the height of its child widget.

Customize Flutter Card Height (2 Methods)

There are two ways for customizing the Flutter card height. See below:

Flutter Padding Widget
Flutter SizedBox Widget

Flutter Padding Widget

First method is to use the Flutter padding widget. Its used to create a distance/space between the borders of card and the card’s child widget. We have to wrap the child widget with padding and specify the padding properties.

We also have given our card widget a background color so the changes can be seen clearly.

Let’s now customize Flutter card height using padding widget. See below code:

Card(
       color: Colors.blue,
           child: Padding(
              padding: const EdgeInsets.symmetric(
                    vertical: 26, horizontal: 10),
                     child: Text(
                        'Custom Flutter Card Height',
                        style: TextStyle(color: Colors.white),
                      ),
                    ))

You can see that the height of Flutter card widget is successfully customized by the use of Flutter padding widget.

Flutter SizedBox Widget

We can also customize the height of Flutter card widget by wrapping the card with Flutter SizedBox widget.

Let’s now customize our Flutter card height using sizedBox widget. See below code:

SizedBox(
      height: 50,
      child: Card(
          color: Colors.blue,
          child: Text(
            'Custom Flutter Card Height',
            style: TextStyle(color: Colors.white),
          )),
    )

So this is how you can easily customize Flutter card height.

Difference between these two methods is that the height will increase if the size of child widget increases when using the padding method while the height will remain fixed when using the sizedBox method.

Hope you like this post. Do give these methods a try and share your experience here.

If you still have any questions related to the customization of Flutter card height, then do let me know in the comment section. I’d be very glad to answer all.

The complete source code is given in the next section in which both the methods are implemented to customize Flutter card height.

Custom Flutter Card Height Source Code

import 'package:flutter/material.dart';
void main() {
  runApp(const MyApp());
}
class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Homepage(),
    );
  }
}
class Homepage extends StatefulWidget {
  @override
  State<Homepage> createState() => _HomepageState();
}
class _HomepageState extends State<Homepage> {
  @override
  Widget build(BuildContext context) {
    return SafeArea(
        child: Scaffold(
            body: Center(
                child: SizedBox(
      height: 50,
      child: Card(
          color: Colors.blue,
          child: Padding(
            padding: const EdgeInsets.all(8.0),
            child: Text(
              'Custom Flutter Card Height',
              style: TextStyle(color: Colors.white),
            ),
          )),
    ))));
  }
}
