If anyone wants details for any widget, you can ask me.如果有人想要任何小部件的详细信息,可以问我。
在<application>
启动之前,将以下权限添加到android/app/src/main/AndroidManifest.xml
:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
I had the same error.我有同样的错误。 I looked through my code and found that I had given the wrong collection name while I was calling firebasefirestore.
我查看了我的代码,发现我在调用 firebasefirestore 时给出了错误的集合名称。 Please do check that you are providing the right reference names to collections and docs.
请务必检查您是否为集合和文档提供了正确的参考名称。
I see this error when wireless is active but the connection to Firestore fails.当无线处于活动状态但与 Firestore 的连接失败时,我会看到此错误。 For example, when debugging I connect to the local emulators, if I forget to start the emulator I get this message, but the app still works from cache.
例如,在调试时我连接到本地模拟器,如果我忘记启动模拟器,我会收到此消息,但该应用程序仍然可以从缓存中运行。
just make sure you are calling the right instance name from firestore for me i was calling medicinal product in the instace and i had defined MedicineProductData int the firebase database so correcting it to the MedicineProductData solved my issue只要确保你从firestore为我调用了正确的实例名称我在instace中调用了医药产品,我已经在firebase数据库中定义了MedicineProductData,因此将其更正为MedicineProductData解决了我的问题
code: QuerySnapshot value = await FirebaseFirestore.instance.collection("MedicineProductData").get();代码:QuerySnapshot 值 = 等待 FirebaseFirestore.instance.collection("MedicineProductData").get();
Yes, I solve this.是的,我解决了这个问题。 I have also face this probelem.
我也遇到过这个问题。
Why it comes?为什么会来? It's because your emulator doesn't have internet connection.
这是因为您的模拟器没有互联网连接。 Though it is showing wifi connection.
虽然它显示wifi连接。
