如何调整cupertinoAppBar领先图像的大小

Question

你好，我试图调整图像的大小，但我却无法按照Resize leading widget in flutter AppBar
进行操作 但是在cupertinoNavigationBar的情况下不起作用。我在这里缺少什么。

class ProductOverViewScreen extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    if (Platform.isIOS) {
      return CupertinoPageScaffold(
        backgroundColor: Colors.grey[300],
        navigationBar: CupertinoNavigationBar(
          automaticallyImplyLeading: false,
          leading: Row(
            mainAxisAlignment: MainAxisAlignment.start,
            crossAxisAlignment: CrossAxisAlignment.center,
            children: [
              SizedBox(
                width: 100,
                height: 100,
                child: Image.asset(
                  'assets/images/logo.png',
                ),
              ),
              Container()
            ],
          ),
          backgroundColor: AppColors.red,
          trailing: Row(mainAxisAlignment: MainAxisAlignment.end, children: [
            Icon(
              Icons.shopping_cart,
              color: Colors.white,
            ),
            SizedBox(width: 10),
            GestureDetector(
              child: Icon(
                Icons.search,
                color: Colors.white,
              ),
              onTap: () {
                print('presse');
              },
            ),
          ]),
        ),
        child: _buildContent(context),
      );
    }
