android - pub get failed: 因为flutter_app依赖firebase_firestore ^0.12.7+1 不匹配任何版本，版本解析失败

问题描述

 pub get failed: Because flutter_app depends on firebase_firestore
 ^0.12.7+1 which doesn't match any versions, version solving failed.

尝试flutter pub get在 pubspec.yaml 文件中运行时出现此错误。我目前正在尝试设置 firebase https://firebase.google.com/docs/flutter/setup。

这是我的 pubspec.yaml 文件：

name: flutter_app
description: A new Flutter application.

version: 1.0.0+1

environment:
  sdk: ">=2.1.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter

  # The following adds the Cupertino Icons font to your application.
  # Use with the CupertinoIcons class for iOS style icons.
  cupertino_icons: ^0.1.2

  # Add the dependency for the Firebase Core Flutter SDK
  firebase_core: ^0.4.0+1

  # Add the dependency for the FlutterFire plugin for Google Analytics
  firebase_analytics: ^4.0.2

  # Add the dependencies for any other Firebase products you want to use in your app
  # For example, to use Firebase Authentication and Cloud Firestore
  firebase_auth: ^0.11.1+3
  firebase_firestore: ^0.12.7+1

dev_dependencies:
  flutter_test:
    sdk: flutter


# For information on the generic Dart part of this file, see the
# following page: https://dart.dev/tools/pub/pubspec

# The following section is specific to Flutter.
flutter:

  # The following line ensures that the Material Icons font is
  # included with your application, so that you can use the icons in
  # the material Icons class.
  uses-material-design: true

构建.gradle：

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'

        classpath 'com.google.gms:google-services:3.2.1'
    }
}

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

rootProject.buildDir = '../build'
subprojects {
    project.buildDir = "${rootProject.buildDir}/${project.name}"
}
subprojects {
    project.evaluationDependsOn(':app')
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

build.gradle 应用程序：

def localProperties = new Properties()
def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) {
    localPropertiesFile.withReader('UTF-8') { reader ->
        localProperties.load(reader)
    }
}

def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) {
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")
}

def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) {
    flutterVersionCode = '1'
}

def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) {
    flutterVersionName = '1.0'
}

apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

android {
    compileSdkVersion 28

    lintOptions {
        disable 'InvalidPackage'
    }

    defaultConfig {
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.example.flutter_app"
        minSdkVersion 16
        targetSdkVersion 28
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.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
        }
    }
}

flutter {
    source '../..'
}

dependencies {
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
}

apply plugin: 'com.google.gms.google-services'

我注意到第二个 build.gradle 文件包含几个标记的错误，但我不确定这是否意味着什么。

感谢您的帮助！

解决方案

firebase_firestore 包已被弃用，它的最后一个版本是 0.0.3+1...所以它找不到版本 ^0.12.7+1

您将需要改为 cloud_firestore：

https://pub.dev/packages/cloud_firestore
