让 Wrap 组件里的多个控件可以滚动

将 Wrap 控件放在 SingleChildScrollView 控件里面.

SingleChildScrollView(
    scrollDirection: Axis.vertical,
    child: Wrap(
      direction: Axis.horizontal,
      spacing: 8,
      runSpacing: 12,
      children: [
        _buildImageCard('abc'),
        _buildImageCard('def'),
        _buildImageCard('ghi'),
        _buildImageCard('jkl'),
        _buildImageCard('jkl'),
        _buildImageCard('jkl'),
        _buildImageCard('jkl'),
      ],
    ),
  );
