Details
Mobile applications often need to collect user input and need to interact with users. In this course, you’ll learn to collect this input and handle interaction with the help of Flutter. You’ll discover the types of input widgets you can use to accept input and explore use cases and special characteristics of each input type. In addition, you’ll learn to detect and handle gestures using built-in widgets.
Result
After completing this course, you’ll be able to use the different tools and features Flutter offers to collect input and handle user interaction.
Prerequisites
No formal prerequisites. However, some prior knowledge about the topic is highly recommended.

Forms and Animations with Flutter
Forms and Animations with Flutter: Working with Input Widgets & Forms
Mobile applications often need to collect user input. User input
- in Flutter is collected using input widgets and these input widgets
- can be embedded in forms. In this course, you will discover the
- types of input widgets you can use to accept input. You will
- explore use cases and special characteristics of each input type
- and how inputs can be grouped together into forms with a submit
- button. Next, you will implement and handle changes in a variety of
- inputs. You will use change handlers to handle input changes and
- state updates and use grouped widgets to update the same state
- using multiple inputs. Finally, you will see how input widgets can
- be embedded as part of Flutter forms. You will learn how form state
- is accessed and validated using form field widgets and how you can
- create custom widgets that can be embedded in Flutter forms.
Forms and Animations with Flutter: Detecting & Handling Gestures
Users often interact with mobile devices using gestures, which
- are semantic actions that can update the state of the application.
- Flutter makes it easy to detect and handle gestures using built-in
- widgets. In this course, you will discover how the GestureDetector
- in Flutter helps you detect motions in your app that are gestures.
- The GestureDetector allows you to configure callbacks for the
- specific gestures you want to handle and allows you to detect and
- respond to these gestures. If multiple gesture detectors are
- activated, Flutter uses the gesture arena to disambiguate and
- invoke the callback on the right gestures. Next, you will explore
- how to implement gesture detection in your application. You will
- learn to handle tap, long press, double tap, and drag-related
- gestures. You will also configure callbacks for other states in the
- gesture lifecycle such as the start or end of a gesture. Finally,
- you will see how you can override the default behavior of the
- gesture arena by configuring a raw gesture detector that allows
- multiple winners in the arena.
Forms and Animations with Flutter: Implementing & Configuring Animations
Mobile applications can be made fun, interactive, and
- interesting using animations. Animations add continuity to
- transitions that you make in your application and make them more
- intuitive for users. Flutter offers built-in animatable widgets
- known as implicitly animated widgets while at the same time giving
- you the tools that you need to build your own custom advanced
- animations. In this course, you will explore how animations provide
- an illusion of motion and how Flutter makes animating widgets
- straightforward using implicit animations. Next, you will explore
- implicit animations using a variety of animatable widgets such as
- the AnimatedContainer, AnimatedOpacity, AnimatedCrossFade, and
- AnimatedSlide. You will learn to create and manage explicit
- animations that use the AnimationController and how to generate the
- right property values for your animations using tweens. You will
- also see how the AnimatedBuilder improves the performance of your
- animations. Finally, you will explore a range of animations such as
- Hero animations, staggered animations, and physics simulations that
- animate objects using the laws of physics.
Course options
We offer several optional training products to enhance your learning experience. If you are planning to use our training course in preperation for an official exam then whe highly recommend using these optional training products to ensure an optimal learning experience. Sometimes there is only a practice exam or/and practice lab available.

Optional practice lab
To supplement this training course you may add a special practice lab. You perform the tasks on real hardware and/or software applicable to your Lab. The labs are fully hosted in our cloud. The only thing you need to use our practice labs is a web browser. In the LiveLab environment you will find exercises which you can start immediately. The lab enviromentconsist of complete networks containing for example, clients, servers,etc. This is the ultimate way to gain extensive hands-on experience.
