I am trying to use the widget marquee and this is the code : Marquee( text: 'Some sample text that takes some space.', style: TextStyle(fontWeight: FontWeight.bold), scrollAxis: Axis.horizontal, crossAxisAlignment: CrossAxisAlignment.start, blankSpace: 20.0, velocity: 100.0, pauseAfterRound: Duration(seconds: 1), showFadingOnlyWhenScrolling: true, fadingEdgeStartFraction: 0.1, fadingEdgeEndFraction: 0.1, numberOfRounds: 3, startPadding: 10.0, accelerationDuration: Duration(seconds: 1), accelerationCurve: Curves.linear, decelerationDuration: Duration(milliseconds: 500), decelerationCurve: Curves.easeOut, ); and this is the error : - Acceleration and deceleration phase overlap. To fix this, try a combination of these approaches:

• Make the text longer, so there's more room to animate within.
• Shorten the accelerationDuration or decelerationDuration.
• Decrease the velocity, so the duration to animate within is longer. 'package:marquee/marquee.dart': Failed assertion: line 631 pos 9: '_linearDuration >= Duration.zero'

Set the blankSpace value to non-0
