Hello, fellow Flutter enthusiasts! Today we have something exciting to delve into. We will unwrap the widely popular Flutter package - Flutter Speed Dial (Flutter_speed_dial). This mighty package empowers us to implement an appealing and dynamic Material Design Speed Dial with labels, animated icons, multi-directional children, and much more.
Flutter Speed Dial is not merely a tool but an omnipotent weapon in a Flutter developer’s arsenal. It instills potency in our apps to branch out multiple options from a single FloatingActionButton widget, imitating the 'speed dial' feature available in many phone apps.
Getting the Flutter Speed Dial set up in your environment is straightforward. Add the Flutter_speed_dial package to your pubspec.yaml like so:
1dependencies: 2 flutter_speed_dial: ^latest_version
After adding the package, don't forget to fetch the dependencies with the Flutter packages get command.
Remember to import the package at the top of your Dart file:
1import 'package:flutter_speed_dial/flutter_speed_dial.dart';
Flutter Speed Dial has incredible features, making it a coveted package among developers. This section will delve into its key features and understand how to utilize them effectively in your Flutter projects.
In coherence with the Flutter mantra of beautiful interfaces, Flutter Speed Dial adheres to Material Design guidelines, making your app more visually appealing. A vibrant FloatingActionButton bursting out to display other actions–the very notion of it adds a layer of sophistication to your app's UX.
Animated icons bring your speed dial to life. These animated icons are an integral part of the Flutter Speed Dial experience. They provide visual cues for the action taking place - extending a list of options or collapsing them.
The AnimatedIconData widget is a 'const icon' that defines the animated icons used within Flutter Speed Dial. The const icon is handy as it provides an established set of animations for a given visual.
1SpeedDial( 2 animatedIcon: AnimatedIcons.menu_close, 3 animatedIconTheme: IconThemeData(size: 22.0), 4);
AnimatedIconTheme is provided so you can easily adjust icon size and color. We can change the 'icon color' via the AnimatedIconTheme.
1SpeedDial( 2 animatedIconTheme: IconThemeData(size: 22, color: Colors.white), 3);
The Floating Action Button (FAB) is a recognizable component in Material Design. It's often used for an application's primary action; pairing it with a Flutter Speed Dial brings your button press to life. Implementing a FloatingActionButton widget with Speed Dial is as simple as below:
1SpeedDial( 2 child: Icon(Icons.add), 3 animatedIcon: AnimatedIcons.menu_close, 4 overlayColor: Colors.black, 5 overlayOpacity: 0.5, 6 children: [ 7 SpeedDialChild(child: Icon(Icons.accessibility), label: 'First'), 8 SpeedDialChild(child: Icon(Icons.brush), label: 'Second'), 9 SpeedDialChild(child: Icon(Icons.code), label: 'Third'), 10 ], 11);
One of the intriguing factors about Flutter Speed Dial is how it facilitates an FAB menu. It allows children, each of whom includes SpeedDialChild() widgets, to be showcased as options. The SpeedDialChild() allows parameters like child, label, and onTap, thus giving control over each option in the FAB menu.
1SpeedDial( 2 // Other properties... 3 children: [ 4 SpeedDialChild( 5 child: Icon(Icons.accessibility), 6 label: 'First', 7 onTap: () => print('FIRST CHILD'), 8 ), 9 // More children... 10 ], 11);
Multidirectional children are another exceptional feature Flutter Speed Dial offers, enhancing the speed dial experience. It allows the developer to set the direction of the children popping out of the FloatingActionButton widget. This attribute is controlled by the direction property of the package, which ensures a visually pleasing experience when users interact.
1SpeedDial( 2 direction: SpeedDialDirection.Up, 3 // Other properties... 4 children: [ 5 // Your SpeedDialChild goes here... 6 ], 7);
As you can observe, we have many directions to set, such as SpeedDialDirection.Up, SpeedDialDirection.Down, SpeedDialDirection.Left, or SpeedDialDirection.Right.
We can follow certain practices to unlock Flutter Speed Dial's maximum potential. Let's look at a few of them:
1SpeedDialChild( 2 child: Icon(Icons.accessibility), 3 label: 'Profile', 4 onTap: () => print('Profile Tapped'), 5),
These practices help you create a fluid UX with the Flutter Speed Dial.
From this comprehensive exploration, it's clear that Flutter Speed Dial is a nifty tool that empowers developers to create visually appealing, intuitive, and dynamic applications in Flutter. It's high on aesthetics, extremely flexible, and allows you to create app interfaces that captivate users.
With its range of customizable parameters, the Flutter Speed Dial provides developers with extensive control over the look and feel of FABs. Grasping and implementing its basics and optimization tips will bear fruit in your Flutter projects.
