在模拟器中使用图像选择器上传图像时出错 - Flutter 应用程序

Question

Please how can I fix this error? I use the image picker but when I select the image in the gallery from the emulator it doesn't appear.

Here is the complete error text:

I think, that this string: "Google Play services out of date for com.example.chat_app. Requires 12451000 but found 11743470" says about use out of dated version of Android needed to using widget.

try to use newer version of Android in your emulator.
