Auto Step for Flutter

Auto Step is a Flutter widget that facilitates the animation of components by automatically stepping through a sequence of values. It is particularly useful for creating animations or transitions within your Flutter applications.

AutoStep Widget

Usage

AutoStep(
  total: 3,
  duration: Duration(milliseconds: 1000),
  builder: (step) => AnimatedContainer(
              duration: Duration(milliseconds: 500),
              width: 100.0 * step,
              height: 100,
              color: Colors.green,)
)

Parameters

• total: The total number of steps in the sequence.
• duration: The duration for each step in the sequence.
• builder: A function that builds the UI for each step based on the current step index.
• loopMode: An instance of AutoStepLoopMode specifying the looping behavior. Default is AutoStepLoop().

AutoStepSwitch Widget

Usage

AutoStepSwitch(
  duration: Duration(milliseconds: 3000),
  builder: (step) => AnimatedAlign(
      alignment: step
          ? Alignment.centerLeft
          : Alignment.centerRight,
      duration: Duration(milliseconds: 2000),
      child: Container(
          width: 64,
          height: 64,
          decoration: BoxDecoration(
              shape: BoxShape.circle, 
              color: Colors.red
          ),
      ),
  )
)

Parameters

• duration: The duration for each step in the sequence.
• builder: A function that builds the UI for each step based on the current step status (true/false).
• loop: (Optional) Indicates whether the sequence should loop back to the beginning after reaching the last step. Default is AutoStepLoop().

AutoStepValues Widget

Usage

AutoStepValues<BoxDecoration>(
  values:  [
    BoxDecoration(
      shape: BoxShape.rectangle,
      color: Colors.red
    ),

    const BoxDecoration(
      shape: BoxShape.circle,
      color: Colors.green
    ),

    const BoxDecoration(
      shape: BoxShape.rectangle,
      color: Colors.blue
    ),

    BoxDecoration(
      shape: BoxShape.circle,
      color: Colors.white,
      border: Border.all(color: Colors.black)
    ),

  ],
  duration: List.generate(4, (index) => const Duration(milliseconds: 1000)),
  builder: (step) => AnimatedContainer(
    duration: const Duration(milliseconds: 500),
    decoration: step,
    width: 100,
    height: 100,
  )
)

Parameters

• values: A list of values of type T representing the sequence of steps.
• duration: A list of Duration objects specifying the duration for each step in the sequence.
• builder: A function that takes a value of type T as input and returns a Widget to be rendered for that step.
• loopMode: An instance of AutoStepLoopMode specifying the looping behavior. Default is AutoStepLoop()

AutoStepLoopMode

Description

AutoStepLoopMode provides different looping modes for the widget.

Loop Modes

• AutoStepNoLoop : Stops the sequence without looping.
• AutoStepLoop : Loops the sequence a specified number of times or infinity.
• AutoStepReverseLoop : Reverses the sequence after reaching the end and loops a specified number of times or infinity.
