Speed up recording after generating gif

[tudosxxx]

Added this widget on the videoplay, then recorded, and the final generated gif speeded up

`

SizedBox( width: w-80, height: h-80, child: ListView.builder( itemCount: h~/10 - 8, padding: EdgeInsets.zero, physics: const NeverScrollableScrollPhysics(), shrinkWrap: true, itemBuilder: (context,index){ return SizedBox( height: h/10 - 8, child: ListView.builder( itemCount:w~/10 - 8, padding: EdgeInsets.zero, physics: const NeverScrollableScrollPhysics(), shrinkWrap: true, scrollDirection: Axis.horizontal, itemBuilder: (ctx,ind){ return ClipRRect( child: Container( width: w~/10 - 8,height: h~/10 - 8, color: listcolor[Random().nextInt(listcolor.length-1)], child: Stack( children: [ Positioned.fill( child: BackdropFilter( filter: ImageFilter.blur(sigmaX: 10, sigmaY: 10), child: Text(''), ) ), ], ) ), ); }, ), ); }, ), )

I test，too many widget will speed。

Strangely, it is shown in my app that it is accelerated. Save it to Samsung mobile phone, and the album will open normally. Move to the computer window and open it to see if it is accelerated. Now the web page looks normal.
