velocity value would not be Effective right now

i try to wacth the value if velocity by provider,
when the velocity value change the speed will be effective always need the text play one times

 Selector<AllOne,Tuple5<String ,int,double,double,double >>(
                      shouldRebuild: (pre,next){
                        return pre!=next;
                      },
                      builder: (context, Tuple4Value, child) {
                        print('builderpriview${ Tuple4Value.item4}');
                        return  Marquee(
                          text:Tuple4Value.item1,
                          style: TextStyle(
                              color: GlobalConfig.colorList[Tuple4Value.item2], // fontSize: allone.currentFontSize,
                              letterSpacing: Tuple4Value.item5, fontSize: Tuple4Value.item3),
                          scrollAxis: Axis.horizontal,
                          velocity: Tuple4Value.item4,
                        );
                      }, selector: (context, setC)=>Tuple5(setC.displaytext,setC.textColorIndex,setC.fontsizeValue,setC.textSpeed,setC.letterSpacing)),

Thank you for your time

Start with the Marquee widget and the provided Selector example, reproducing the case where Tuple5.item4 changes after the widget is built. Trace how the velocity value is consumed and determine how to verify that a provider-driven velocity change takes effect without requiring the text to play again.
