Hi friends, we will learn how to use the fly_animation flutter package to animate a single widget and multiple widgets from one position to another.

So, let’s get started.

  • animationEndKey: key of the widget where the animation ends. You need to declare and pass GlobalKey to the widget where your animation ends.
  • countOfAnimationWidgets: number of animation widgets that need to be created. countOfAnimationWidgets field value must be greater than 0.
  • topPosition: top position of the animation widget to display on the screen. topPosition value must be greater than or equal to 0.
  • childWidget: widgets tree to be displayed on the screen. The parent widget of the screen must be FlyAnimationWidget. The widget tree that you want to show on the screen must be passed to childWidget field.
  • animationWidget: Its type is Widget so you can pass any widget that you want to animate to this field.
  • animationWidgetWidth: Its value must be greater than 0. The width of the widget that you want to animate.
  • animationWidgetHeight: Its value must be greater than 0. The height of the widget that you want to animate.
  • animationDurationInMillis: animation duration in milliseconds
