所有侧面的 ElevatedButton 填充不会修改

Question

我有一个具有以下属性的 ElevatedButton：我在此处附加了一张照片：https: //i.stack.imgur.com/oH3pO.png

ElevatedButton(
               clipBehavior: Clip.none,
               style: ElevatedButton.styleFrom(
               padding: EdgeInsets.zero,
               minimumSize: Size(0, 0),
               elevation: 0,
               ),

我修改了周围的填充，但它的最小填充 (_InputPadding) 仍然为 48 像素 x 48 像素。我该如何解决这个问题？

Answer 1

这些填充是因为tapTargetSize属性。要删除它们，请添加tapTargetSize: MaterialTapTargetSize.shrinkWrap,到按钮样式。

例如：

ElevatedButton(
  style: ElevatedButton.styleFrom(
    fixedSize: size,
    padding: const EdgeInsets.zero,
    tapTargetSize: MaterialTapTargetSize.shrinkWrap,
  ),

来自源代码的附加信息。

  /// MaterialTapTargetSize
  ///
  /// Expands the minimum tap target size to 48px by 48px.
  ///
  /// This is the default value of [ThemeData.materialTapTargetSize] and the
  /// recommended size to conform to Android accessibility scanner
  /// recommendations.

  /// Shrinks the tap target size to the minimum provided by the Material
