 SwipeActionCell(
      key: ObjectKey(list[index]),///this key is necessary
      trailingActions: <SwipeAction>[
        SwipeAction(
            title: "delete",
            onTap: (CompletionHandler handler) async {

SwipeActionCell(
      ///this key is necessary
      key: ObjectKey(list[index]),

      ///this is the same as iOS native
      performsFirstActionWithFullSwipe: true,
      trailingActions: <SwipeAction>[
        SwipeAction(
            title: "delete",
            onTap: (CompletionHandler handler) async {
              list.removeAt(index);

            style: TextStyle(fontSize: 40)),
      ),
    );

     performsFirstActionWithFullSwipe: true,
     trailingActions: <SwipeAction>[
       SwipeAction(
           title: "delete",
           onTap: (CompletionHandler handler) async {
             
             /// await handler(true) : will delete this row
             ///And after delete animation,setState will called to 
             /// sync your data source with your UI

             await handler(true);
             list.removeAt(index);

     performsFirstActionWithFullSwipe: true,
     trailingActions: <SwipeAction>[
       SwipeAction(
           title: "delete",

 SwipeActionEditController controller;

///在initState
@override
  void initState() {
    super.initState();
    controller = SwipeActionController();
  }
///To get the selected rows index
List<int> selectedIndexes = controller.getSelectedIndexes();

///toggleEditingMode
controller.toggleEditingMode()

///startEditMode
controller.startEditingMode()

///stopEditMode
controller.stopEditingMode()

///select cell
controller.selectCellAt(indexPaths:[1,2,3])

controller.deselectCellAt(indexPaths:[1,2,3])

///pass your data length to selectedAll
controller.selectAll(30)

///deselect all cell
controller deselectAll()

ListView.builder(
        itemBuilder: (c, index) {
          return _item(index);
        },
        itemCount: list.length,
      );


 Widget _item(int index) {
     return SwipeActionCell(
       ///controller
       controller: controller,
       ///index is required if you want to enter edit mode
       index: index,
       performsFirstActionWithFullSwipe: true,
       key: ValueKey(list[index]),
       trailingActions: [
         SwipeAction(
             onTap: (handler) async {
               await handler(true);
               list.removeAt(index);
               setState(() {});
             },
             title: "delete"),
       ],
       child: Padding(
         padding: const EdgeInsets.all(15.0),
         child: Text("This is index of ${list[index]}",
             style: TextStyle(fontSize: 35)),
       ),
     );
   }

• Example 7：customize shape

Widget _item(int index) {
    return SwipeActionCell(
      key: ValueKey(list[index]),
      trailingActions: [
        SwipeAction(
            nestedAction: SwipeNestedAction(
              ///customize your nested action content

            ///you should set the default  bg color to transparent
            color: Colors.transparent,

            ///set content instead of title of icon
            content: _getIconButton(Colors.red, Icons.delete),

About CompletionHandler in onTap function of SwipeAction

it means how you want control this cell after you tap it. If you don't want any animation,just don't call it and update your data and UI with setState()

If you want some animation:

• handler(true) : Means this row will be deleted(You should call setState after it)

• await handler(true) : Means that you will await the animation to complete(you should call setState after it so that you will get an animation)

• handler(false) : means it will not delete this row.By default,it just close this cell's action buttons.

• await handler(false) : means it will wait the close animation to complete.

About all parameter:

I wrote them in my code with dart doc comments.You can read them in source code.
