не могу отправить в облачный пожарный магазин

/ 17 февраля 2019

Я пытаюсь использовать Firebase Cloud Firestore в моем проекте флаттера

Я хочу отправить имя пользователя таким способом 

final DocumentReference reference = Firestore.instance.collection('users').document('info');
@override
  void initState() {
    reference.setData({'name':widget.username});
    super.initState();
  }

, но у меня всегда возникает эта проблема

это потому, что я что-то забыл или мой код верен?Окно запуска:

Я попробовал это посвящение, которое minshond здесь Flutter: компонент Firestore отсутствует

, но не работал

Вы можете сделать функцию как myFunc () {} и установить данные облака в этой функции.После этого вызовите функцию в initstate () {}.

 final DocumentReference reference = Firestore.instance.collection('users').document('info');

      _myFunc() async {
        reference.setData({'name':_userName.text}).whenComplete((){
          print('Data updated in Cloud.');
        });
      }

void initState() {
    _myFunc();
    super.initState();
}

У меня возникла эта проблема, но в моем случае я не указал версию cloud_firestore.Вместо этого я оставил поле пустым «cloud_firestore:», как объяснено в Официальном флаттере videos .Однако, если вы не укажете номер версии, похоже, что загружена самая последняя.Тем не менее, похоже, что последняя версия не совместима с AndroidX и не работает понижение версии.

Я решил эту проблему, создав новый проект Flutter в Android Studio и включив совместимость с Kotlin и Swift на начальном экране конфигурации проекта.

Затем в pubspec.yaml я набрал следующий код: 

dependencies:

  firebase_core: 0.2.5+1
  cloud_firestore: 0.8.2+3

Более того, похоже, что ваш pubspec.yaml не имеет зависимости firebase_core.

Это сборка для моего приложения: 

android {
    compileSdkVersion 28

    sourceSets {
        main.java.srcDirs += 'src/main/kotlin'
    }

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.organization.app"
        minSdkVersion 21
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.debug
        }
    }
}
//The following line must be placed at the end of the file
apply plugin: 'com.google.gms.google-services'

И это сборка для моего проекта: 

buildscript {
    ext.kotlin_version = '1.2.71'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:3.2.1'
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

Я понимаю, что это решение может быть не самым эффективным.Специально, учитывая, что вам, возможно, придется создать новый проект Flutter.Тем не менее, как только новый проект будет создан, как упоминалось выше, вы можете скопировать свои старые файлы дротиков Flutter в новый.

Надеюсь, это поможет вам.

Вы пытались понизить зависимость cloud_firestore?Я видел пару сообщений на эту тему совсем недавно, все из которых используют cloud_firestore 9.0 + 2.
