Flutter：如何删除 CupertinoDatePicker 中的分隔线？

Question

在进行编码演练时，我一直没有找到摆脱分隔线的方法。我怎样才能做到这一点？有关更多信息，我刚刚通过复制 CupertinoDatePicker class.

由于您复制了 CupertinoDatePicker class 只需从 picker.dart 中删除 _buildMagnifierScreen() 方法中的边框 /src/cupertino/

/// Draws the magnifier borders.
  Widget _buildMagnifierScreen() {
    final Color resolvedBorderColor = CupertinoDynamicColor.resolve(_kHighlighterBorder, context);

    return IgnorePointer(
      child: Center(
        child: Container(
          decoration: BoxDecoration(
            // remove this attribute
            border: Border(
              top: BorderSide(width: 0.0, color: resolvedBorderColor),
              bottom: BorderSide(width: 0.0, color: resolvedBorderColor),
            ),
          ),
          constraints: BoxConstraints.expand(
            height: widget.itemExtent * widget.magnification,
          ),
        ),
      ),
    );
  }
