How to display snackbar infinite duration in flutter?
You can use the Duration property on the snackbar
Example
final snackBar = SnackBar( content: Text('Cart:'+countProducts.toString()+" Products($countCost:sum)",style: TextStyle(color: Colors.black),), shape: RoundedRectangleBorder( borderRadius: BorderRadius.only(topLeft:Radius.circular(22),topRight:Radius.circular(22))), backgroundColor: Colors.white70, action: SnackBarAction( textColor: Colors.blueAccent, label: "Buy", onPressed: () { // Some code to undo the change. }, ), duration: Duration(seconds: double.infinity),//Gets problem int != double );
using Duration(seconds: double.infinity)
Not Sure if this is the best though.
EDIT
You can try the following instead of using double.infinity
Duration(days: 365)Reference
