随着文本的增长,我想要包装文本.我搜索并尝试用几乎所有东西包裹,但仍然文本保持一行并从屏幕溢出.有谁知道如何实现这一目标？任何帮助都非常感谢!

Positioned(
    left: position.dx,
    top: position.dy,
    child: new Draggable(
      data: widget.index,
      onDragStarted: widget.setDragging,
      onDraggableCanceled: (velocity, offset) {
        setState(() {
          position = offset;
          widget.secondCallback(offset, widget.index);
          widget.endDragging();
        });
      },
      child: new GestureDetector(
        onTap: () {
          widget.callback(widget.caption, widget.index);
        },
        child: new Text(
            widget.caption.caption,
            style: new TextStyle(
              color: widget.caption.color,
              fontSize: widget.caption.fontSize,
            ),
          ),
      ),
      feedback: new Material(
        type: MaterialType.transparency,
        child: new Text(
          widget.caption.caption,
          style: new TextStyle(
              color: widget.caption.color,
              fontSize: widget.caption.fontSize),
          softWrap: true,
        ),
      ),
    ));
