🎮 SpringController

SpringController allow you to control the animations without setting the setState.

//initial anim = Motion.play
final SpringController springController =
     SpringController(); 
// you can set the initial anim using initialAnim param..
final SpringController springController =
      SpringController(initialAnim: Motion.pause,);

Controlling the animations

GestureDetector(
          onTap: () {
            springController.play(
                motion: Motion.reverse,
                animDuration: Duration(milliseconds: 300),
                curve: Curves.bounceIn,
                delay: Duration(milliseconds: 900));
          },
          child: Spring.slide(
              springController: springController,
              slideType: SlideType.slide_in_right,
              delay: Duration(milliseconds: 500),
              animDuration: Duration(milliseconds: 1000),
              curve: Curves.easeInExpo,
              extend: 30,
              withFade: true,
              animStatus: (AnimStatus status) {
                print(status);
              },
              child: FlutterLogo()),
        ),

🔈 Animation Status

You can listen for animation Staus via animStatus callBack which returns AnimStatus enum.

• AnimStatus.forward
• AnimStatus.completed
• AnimStatus.reverse
• AnimStatus.dismissed

Spring.rotate(
     springController: springController,
     animStatus: (AnimStatus status) {
          print(status);
     },
     child: FlutterLogo()),
