小编Fei*_*ang的帖子

我正在使用 Navigator 的声明式方法：

Navigator(
      pages: [
        MaterialPage(child: _screen),
      ],
      onPopPage: (route, result) {
        return route.didPop(result);
      },
);

如何在屏幕之间添加过渡？

我使用 Image.network() 显示来自 URL 的图像，这就是我使用它的方式

Image image = Image.network(
      _auth.currentUser!.photoURL!,
      width: 100.getWidth(context),
      height: 100.getWidth(context),
      frameBuilder: (context, child, frame, wasSynchronouslyLoaded) {
        return wasSynchronouslyLoaded
            ? child
            : _profileImagePlaceholder(context);
      },
      loadingBuilder: (context, child, loadingProgress) {
        return loadingProgress == null
            ? child
            : _profileImagePlaceholder(context);
      },
      errorBuilder: (context, error, stackTrace) {
        return _profileImagePlaceholder(context);
      },
    );

但即使当我设置 errorBuilder 甚至用 try/catch 包装整个事情时这NetworkImageLoadException仍然显示

完全例外

The following NetworkImageLoadException was thrown resolving an image codec:
HTTP request failed, statusCode: 403,
