颤振相机出现拉伸 [英] Flutter camera appears stretched

问题描述

我一直在玩颤振，到目前为止我很喜欢它，但我在让相机工作时遇到问题.

I've been playing around with flutter an i'm loving it so far, but I'm having an issue getting the camera working.

我按照此页面上的说明操作 https://pub.dartlang.org/packages/camera 并且有效.但是，相机被拉伸以适合手机屏幕，但图像变形并且比应有的高度更高.其他使用相机的应用似乎保持比例，有没有办法确保它不会被拉伸但仍会填满屏幕?

I follow the directions on this page https://pub.dartlang.org/packages/camera and it works. However, the camera is stretched so that it fits the phone screen, but the image is warped and taller than it should be. Other apps which use the camera seem to keep it in proportion, is there a way to ensure that it doesn't get stretched but still fills the screen?

推荐答案

在 lase 的解决方案的基础上，这是可行的即使设备的纵横比与相机的比例不同:

Building upon the solution by lase, this works even when the aspect ratio of the device is different then the camera ratio:

final size = MediaQuery.of(context).size;
final deviceRatio = size.width / size.height;
return Transform.scale(
  scale: controller.value.aspectRatio / deviceRatio,
  child: Center(
    child: AspectRatio(
      aspectRatio: controller.value.aspectRatio,
      child: CameraPreview(controller),
    ),
  ),
);
