Crafting Beautiful Floating Action Buttons in Flutter

Creating Floating Action Buttons in Flutter

Floating action buttons are a great way to add extra action and functionality to your Flutter app. In this tutorial, we will look at how to create and style floating action buttons in Flutter.

Creating the FloatingActionButton Widget

In order to get started with creating a FloatingActionButton, you will first need to add the material library to your project. The material library provides access to the FloatingActionButton widget. After you've added the material library, you can create the FloatingActionButton widget like so:

// Create a FloatingActionButton
FloatingActionButton myFab = FloatingActionButton(
  child: Icon(Icons.add),
  onPressed: () { 
    // Do something when button is pressed
  },
);

The FloatingActionButton will accept a required child parameter that will determine what icon it displays. It also takes an optional onPressed parameter that will execute a function when the button is pressed. Now that we have our FloatingActionButton created, let's look at how to style it.

Styling the FloatingActionButton

Once you have your FloatingActionButton created, you can start styling it. The FloatingActionButton has many properties available to customize it, such as the background color, the elevation level and the shadow color. Here are a few examples of how to customize your FloatingActionButton:

FloatingActionButton myFab = FloatingActionButton(
  child: Icon(Icons.add),
  backgroundColor: Colors.red,
  elevation: 6.0,
  onPressed: () { 
    // Do something when button is pressed
  },
);

Adding a Tooltip to the FloatingActionButton

You can also add a tooltip to your FloatingActionButton so that it displays a message when the user hovers over it. To do this, you can wrap your FloatingActionButton in a Tooltip widget like so:

Tooltip(
  message: 'Create a new item',
  child: FloatingActionButton(
    child: Icon(Icons.add),
    onPressed: () { 
      // Do something when button is pressed
    },
  ),
);

By wrapping the FloatingActionButton widget with the Tooltip widget, you can now display a message when the user hovers over the button.

And that's it! You now know how to create and style FloatingActionButtons in Flutter. Be sure to check out the official Flutter documentation for more information on how to use FloatingActionButtons in your app.
