[githubkind]

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
