flutter 3.7.0 有什么可以替代FocusTrap？

Question

我将 flutter 更新到 3.7.0，发现 FocusTrap 小部件已被删除。

我可以用什么代替它？ 例如来自 pinput 库的源代码：

return _PinputFormField(
      enabled: isEnabled,
      validator: _validator,
      child: FocusTrap(
        focusNode: effectiveFocusNode,
        child: MouseRegion(
          cursor: _effectiveMouseCursor,
          onEnter: (PointerEnterEvent event) => _handleHover(true),
          onExit: (PointerExitEvent event) => _handleHover(false),
          child: IgnorePointer(
            ignoring: !isEnabled || !widget.useNativeKeyboard,
            child: AnimatedBuilder(
              animation: _effectiveController,
              builder: (_, Widget? child) => Semantics(
                maxValueLength: widget.length,
                currentValueLength: _currentLength,
                onTap: widget.readOnly ? null : _semanticsOnTap,
                onDidGainAccessibilityFocus: handleDidGainAccessibilityFocus,
                child: child,
              ),
              child: _gestureDetectorBuilder.buildGestureDetector(
                behavior: HitTestBehavior.translucent,
                child: Stack(
                  alignment: Alignment.topCenter,
                  children: [
                    _buildEditable(textSelectionControls),
                    _buildFields(),
                  ],
                ),
              ),
            ),
          ),
        ),
      ),
    );

官方替代品是TapRegionSurface ( flutter.dev ) 和TapRegion
