Flutter:找不到providerinstaller的本地模块描述符类 [英] Flutter: Local module descriptor class for providerinstaller not found
问题描述
我一直在尝试开发一款与Firebase兼容的应用程序，但我不是编码专家.
I have been trying to develop an app which works with firebase and I am not a professional of coding.
实际上，我的应用在模拟器上运行良好，但是3-5秒后，我收到一条错误消息，如下所示:
Actually, my app is working well on the emulator but after 3-5 seconds I get an error message as you can see below:
W/DynamiteModule(11855): Local module descriptor class for providerinstaller not found.
I/DynamiteModule(11855): Considering local module providerinstaller:0 and remote module providerinstaller:0
W/ProviderInstaller(11855): Failed to load providerinstaller module: No acceptable module found. Local version is 0 and remote version is 0.
W/DynamiteModule(11855): Local module descriptor class for providerinstaller not found.
I/DynamiteModule(11855): Considering local module providerinstaller:0 and remote module providerinstaller:0

除了当我尝试用相机上传图像时，除了上面的providerinstaller问题外，我还在下面收到其他错误:
In addition to providerinstaller issue above when I try to upload an image with camera, I get additional error below:

您可以在下面查看我的上传页面的代码:
You can see my code of my upload page below:

PickedFile file;
captureImageWithCamera() async {
Navigator.pop(context);
final picker = ImagePicker();
PickedFile imageFile = await picker.getImage(
source: ImageSource.camera,
maxHeight: 680,

如果您想查看我的代码或其他文件，我想与您分享.你能指导我吗?
If you would like to see my code or other files I would like to share with you. Can you please guide me?
谢谢.

推荐答案
我不知道您在哪里访问了Firestore软件包，但就我而言，我试图更新数据，但实际上是在删除并创建一个新的文件.我的代码中没有我需要访问的数据.因此，我唯一的建议是确保您不会意外删除数据或尝试访问不存在或由于某种未知原因而不会拥有的数据，然后转到firestore数据库并确保您的数据是所需的.我已经看到答案，说您需要在模拟器中更新Google服务，所以也许这是您的情况，但是如果您转到设置中的Google Play服务应用并看到停用状态，那不是我的意思，这意味着您的模拟器已经更新，并且它将说更新您的Google Play服务.
i don't know where you accessed the firestore package but in my case i was trying to update data but i was actually deleting and creating a new one which don't have the data i need to access in my code. So my only advice is gone be make sure you are not accidently deleting data or trying to access data you don't or will not have by some unknown reason go to your firestore database and make sure your data is as you want it. I have seen answers saying you need to update your google service in your emulator so maybe that might be your case but its not mine if you go to your google play service app in setting and see deactivate that means your emulator is already updated plus it will say update your google play service.
