【问题描述】：

当我使用 firebase_auth 时，构建成功并且工作正常，当我开始在颤振中包含 image_picker 库时，构建突然崩溃。这些是我尝试运行时遇到的错误：

 J:\flutter_projects\webdoc>flutter run --enable-software-rendering

The plugin firebase_auth could not be built due to the issue above.

项目的版本是

  cupertino_icons: ^0.1.2
  firebase_auth: ^0.15.3
  flushbar: ^1.9.1
  image_picker: ^0.6.2+3
  http: ^0.12.0+2

我什至尝试过使用同样不起作用的 image_picker 0.4.12+1 我尝试设置 jetifier=false，但这并不能解决问题。

Build.gradle 是

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.2'
        classpath 'com.google.gms:google-services:4.0.1'

    }
}

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
}

标签： firebase flutter dart firebase-authentication imagepicker

【解决方案1】：

将android-gradle 更新为以下内容：

dependencies {
classpath 'com.android.tools.build:gradle:3.3.1'
}

并使用最新版本的image_picker，即 0.6.2+3。

如果您还收到以下错误：

未找到 SDK 位置。使用 local.properties 文件中的 sdk.dir 或使用 ANDROID_HOME 环境变量定义位置

那么你需要在终端中执行以下操作：

export ANDROID_HOME="YOUR_SDK_PATH"

【解决方案2】：

将 build.gradle 更新到 3.3.1 版本并使用最新版本的 firebase_auth 和 image_picker，还将分发 url 更改为

distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip

库：

  firebase_auth: ^0.15.3
  image_picker: ^0.6.2+3
