flutter - 固定滑动表对话框在颤动中的位置

Question

我在我的应用程序中使用了一个滑动表对话框，当我想在 inputText 中写一些东西时，一个滑动表就会出现在键盘上。我想固定在底部并将键盘推入滑动板。谁能帮助我，我该如何解决？

这是我与滑动表相关的代码部分：

  Widget buildSheet() {
    return ValueListenableBuilder<String>(
        valueListenable: audioManager.currentEpisodeIdNotifier,
        builder: (_, value, __) {
          var snap = [0.0, 1.0];
          if (value.length > 0) {
            snap = [
              0.2,
              1.0,
            ];
          }
          return SlidingSheet(
            listener: sheetListener,
            duration: const Duration(milliseconds: 500),
            controller: controller,
            color: MyColors.white,
            elevation: 2,
            maxWidth: 500,
            minHeight: 210,
            cornerRadius: 35,
            cornerRadiusOnFullscreen: 0.0,
            closeOnBackdropTap: true,
            closeOnBackButtonPressed: true,
            addTopViewPaddingOnFullscreen: false,
            isBackdropInteractable: true,
            snapSpec: SnapSpec(
              snap: true,
              positioning: SnapPositioning.relativeToAvailableSpace,
              snappings: snap,
              onSnap: (state, snap) {},
            ),
            parallaxSpec: const ParallaxSpec(
              enabled: true,
              amount: 0.35,
              endExtent: 0.6,
            ),
            liftOnScrollHeaderElevation: 4,
            liftOnScrollFooterElevation: 4,
            body: _buildBody(),
            headerBuilder: buildHeader,
            footerBuilder: buildFooter,
            // builder: buildChild,
            customBuilder: buildInfiniteChild,
          );
        });
  }

  Widget buildHeader(BuildContext context, SheetState state) {
    return SizedBox();
  }

  Widget buildFooter(BuildContext context, SheetState state) {
    return SizedBox();
  }

  Widget buildInfiniteChild(
    BuildContext context,
    ScrollController scrollController,
    SheetState state,
  ) {
 return SheetListenerBuilder(
        buildWhen: (oldState, newState) =>
            oldState.progress != newState.progress,
        builder: (context2, snapshot) {
          return Material(
              child: PlayerMain(
                  scrollControllerSheet: scrollController,
                  progress: snapshot.progress));
        });
  }
