            curve: Curves.easeIn, //default Curves.eadInOut
            delay: Duration(milliseconds: 300), //default 0 second
            extend: 30, //default 10
            child: FlutterLogo(size: 100),

withFade

you can set the fade with transaction by enablish withFade=true by default the value is false.

Spring.slide(
   springController: springController,
   slideType: SlideType.slide_in_left,
   withFade: true,
   child: FlutterLogo())

extend

You can extend the length of slide transaction with extend paramater, by deafult extend value is 10 extend is used if the widget size is big. Slide defaulty takes start of the screen. as a starting point.

Spring.slide(
     extend: 30,
     slideType: SlideType.slide_in_left,
     child: FlutterLogo())

• For slide_in the extend value should be positive example( extend=30).
• And for slide_out & reverse transactoins (extend = - 30).

cutomTweenOffset

Offset of spring animation can be customized using customTweenOffset. setting the customTweenOffset ignores the parameter slideType.

Spring.slide(
	slideType: SlideType.slide_in_left,  //ignored
	child: FlutterLogo(),
	cutomTweenOffset: Tween(begin: Offset(-100,0),end: Offset(100,0)))
