Actions

Actions help in handling user gestures (or, touch) inside the app.
For example, when a user taps on a Button, the action that should be performed can be specified from this Actions section.
Some of the common Actions that you can define include On Tap, On Double Tap, On Long Press, and so on.

Types of Action

Most of the widgets can handle three basic types of action:
  • On Tap: Handles the user gesture of a single tap.
  • On Double Tap: Handles the user gesture of double tap.
  • On Long Press: Handles the user gesture of tapping and holding for some time.
Apart from these common types of action, there are a few more action types that can be applied only on some specific widgets:
  • On Submit: This can be applied on a TextField widget. The action will be called when the user indicates that they are done editing the text of the field.
  • On Page Load: This can be applied on the Scaffold widget. The action will get triggered as soon as the page loads.

List of Actions

FlutterFlow allows you to trigger and customize various Actions on any widget. A list of all the available Actions are as follows:

Adding Action

To add an action on the widget:

NOTE: Actions differ according to the widget selected. If you are applying an action on a TextField widget, On Submit gesture will be present. Similarly, if you are applying an action on the Scaffold widget, On Page Load will be available.

Adding Multiple Actions

You can add multiple Actions to the same widget that should trigger on the same or different user gestures.
To add multiple actions:
  1. 1.
    Select the widget on which you want to apply the action.
  2. 2.

Reordering Actions

If you have added multiple Actions for the same user gesture, for say, you add two Actions for the On Tap gesture, then you can order the Actions to specify which Action should be triggered first, followed by the next one, and so on.
To reorder the actions:

    ) to move it upwards or click on the Down Arrow icon (
    ) to move it downwards.
  5. 5.
    After you have Actions in the correct order, click Close.

Document an Action

There's a significant probability you'll forget afterward how or why a specific action was introduced. Additionally, if you work in a team, other builders might want to know more about an action's existence or functioning, especially if it is a complicated one or a custom action.
By documenting an action, you may assist future you and others in remembering why it was included and learn more about the action. It helps you to make any change confidently and ultimately produces fewer bugs.
To document an action, open the action flow editor, select the action, and tap the document icon (
) on the right side, provide the description and save it. Click again to read or modify. You can also view code to see the documentation inside the code.
We will add the documentation inside the code as a comment.
