controller open to manage the state.

[alex-melnyk]

This PR adds the ability to use the controller for the programmatically state management.

@letsar please merge the PR and roll out the new version, this will help me use your plugin from https://pub.dev instead of the git forked version.

Hi, thank you for the PR and sorry for the delay. I'll do this today.

We can already get the SlidableController from the callback since we have the BuildContext, by using Slidable.of(context) :

SlidableAction(
  flex: 2,
  onPressed: (context) {
    Slidable.of(context)?.openEndActionPane();
  },
  backgroundColor: Color(0xFF7BC043),
  foregroundColor: Colors.white,
  icon: Icons.archive,
  label: 'Archive',
),

Is there other use-cases where it would be useful to pass a controller to the Slidable?

You are right, but this adds complexity to managing this controller from the parent widgets. BTW I did find out how to get a controller in another way:

final _slidableKey = GlobalKey();

// some code...
return GestureDetector(
          onSecondaryTap: widget.swipeable && !widget.selectable
              ? () => _slidableController.openEndActionPane()
              : null,
          onLongPress: () => _slidableController.openEndActionPane(),
          child: Slidable(
            key: _slidableKey,
            enabled: widget.swipeable && !widget.selectable,
            endActionPane: ActionPane(
              extentRatio: extentRatio,
              motion: const DrawerMotion(),
              children: [
                if (widget.conversation.contactType.isUnknown)
                  ChatListSlidableAction(
                    label: FlutterI18n.translate(context, 'cta.delete'),
                    backgroundColor: theme.colorScheme.error,
                    onPressed: widget.onDeletePressed,
                    icon: QliqIcons.delete,
                  )
                else ...[
                  ChatListSlidableAction(
                    onPressed: widget.onMutePressed,
                    backgroundColor: AppColors.darkGrey,
                    icon: widget.conversation.isMuted
                        ? QliqIcons.muteConversation
                        : QliqIcons.muteConversation,
                    label: widget.conversation.isMuted
                        ? FlutterI18n.translate(context, 'cta.unmute')
                        : FlutterI18n.translate(context, 'cta.mute'),
                  ),
                  ChatListSlidableAction(
                    onPressed: widget.onStarPressed,
                    backgroundColor: theme.primaryColor,
                    icon: widget.conversation.isStarred
                        ? Icons.star
                        : Icons.star_border,
                    label: widget.conversation.isStarred
                        ? FlutterI18n.translate(context, 'cta.unstar')
                        : FlutterI18n.translate(context, 'cta.star'),
                  ),
                ],
                ChatListSlidableAction(
                  onPressed: widget.onArchivePressed,
                  backgroundColor: AppColors.darkGrey,
                  icon: QliqIcons.archiveConversation,
                  label: FlutterI18n.translate(context, 'cta.archive'),
                ),
              ],
            ),
            child: conversationWidget,
          ),
        );

  /// Since the [Slidable] widget state is private, we need access
  /// to its controller for the ability to open the action pane.
  ///
  /// Returns [SlidableController] from [Slidable] widget state.
  SlidableController get _slidableController =>
      (_slidableKey.currentState as dynamic).controller; // SO HERE is the not-so-good way to get controller, but...

So it will be very helpful if the SlidableState is not private then the global key can be typed properly to access the members such as controller.

Ok I'll merge this then ;-)
