问题描述
我已经在flutter上创建了一个新的应用程序,并且在不同设备之间切换时屏幕尺寸出现了问题.
I've created a new application on flutter, and I've had problems with the screen sizes when switching between different devices.
我使用Pixel 2XL屏幕尺寸创建了该应用程序,并且因为我有一个带有ListView子级的容器,所以要求我提供容器的高度和宽度.
I created the application using the Pixel 2XL screen size, and because I've had containers with a child of ListView it's asked me to include a height and width for the container.
因此,当我将设备切换到新设备时,容器太长并引发错误.
So when I switch the device to a new device the container is too long and throws an error.
我如何才能做到这一点,以便针对所有屏幕对应用程序进行优化?
How can I go about making it so the application is optimized for all screens?
推荐答案
您可以使用:
-
双倍宽度= MediaQuery.of(context).size.width;
-
双倍高度= MediaQuery.of(context).size.height;
要获得仅 SafeArea 的身高(适用于iOS 11及更高版本):
To get height just of SafeArea (for iOS 11 and above):
-
var padding = MediaQuery.of(context).padding;
-
double newheight = height-padding.top-padding.bottom;
