flutter - Flutter TextField ScrollBar 下边距

Question

当我在ScrollBar里面插入一个多行TextField，然后添加很多行，然后滚动到最后，右边的倒带行没有到最后。为什么？

Widget _buildTextField() {
controller = TextEditingController(
  text: text,
);
controller.addListener(_onTextChanged);
return Scrollbar(
  child: TextField(
    style: Styles.headlineRegular(color: ThemeColors.blackText),
    controller: controller,
    maxLines: widget.maxLines,
    minLines: widget.minLines,
    keyboardType: TextInputType.multiline,
    decoration: InputDecoration(
      fillColor: ThemeColors.veryLightGray,
      filled: true,
      hintStyle: Styles.headlineRegular(color: ThemeColors.darkGray),
      hintText: widget.hintText,
      enabledBorder: _buildBorder(ThemeColors.lightGray),
      focusedBorder: _buildBorder(ThemeColors.darkGray),
    ),
  ),
);}
