com.google.android.gms：play-services-maps 已报告版本 16.0.0 已过时

问：

我们有一个电子商务 Flutter 应用程序，它使用flutter_braintree包进行支付网关（PayPal、信用卡等）。

自从dev / devs更新软件包的任何内容以来已经过去了几个月。 今天，当我们尝试在PlayStore上发布更新时，它发出了警告，

The developer of Maps SDK for Android (com.google.android.gms:play-services-maps) has reported version 16.0.0 as outdated. After 90 days from releasing this version of your app, you won't be able to release new versions which contain this SDK until you upgrade to a newer version (17.0.0+).

具有此依赖关系的包原来是flutter_braintree。

现在，问题是，我对 android 开发一无所知，因为我只使用 Flutter。

我现在该怎么办？因为 3 个月后 PlayStore 不允许我发布更新。

我也在包的存储库中问过这个问题。 但我认为我不会很快得到任何回应。

如果有人需要查看它，我已经附上了颤动医生的回应。

这是android/build.gradle文件（我们的应用程序，而不是braintree）

 buildscript {
    ext.kotlin_version= "1.5.31"
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
        classpath 'com.google.gms:google-services:4.3.10'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

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
}

这是 braintree 软件包的 android/build.gradle 文件，

group 'com.example.flutter_braintree'
version '1.0'

buildscript {
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
    }
}

rootProject.allprojects {
    repositories {
        google()
        jcenter()
        maven {
            url "https://cardinalcommerceprod.jfrog.io/artifactory/android"
            credentials {
                username 'braintree'
                password 'abc'
            }
        }
    }
}

apply plugin: 'com.android.library'

android {
    compileSdkVersion 28

    defaultConfig {
        minSdkVersion 21
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    lintOptions {
        disable 'InvalidPackage'
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}

dependencies {
    implementation 'com.braintreepayments.api:drop-in:5.2.1'
    implementation 'com.google.android.gms:play-services-wallet:16.0.1'
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
    components.all {
        allVariants {
            withDependencies { deps ->
                deps.each { dep ->
                    if (dep.group == 'net.minidev' && dep.name =='json-smart') {
                        dep.version {
                            prefer "2.3"
                        }
                        dep.because "resolving dependencies issue"
                    }
                }
            }
        }
    }
}

整个项目中有 2 个名为 ivy.xml 的文件。可以在flutter_braintree（包）项目目录中的 flutter_braintree_master/android/build 文件夹中找到一个，在那里我可以看到以下行：

<dependency org="com.google.android.gms" name="play-services-maps" rev="16.0.0" transitive="false" conf="releaseCompileClasspath-&gt;default"/>

另一个可以在 main_project/ios/.symlinks/plugins/flutter_braintree/android/ivy.xml 的 android/build 文件夹中找到，在那里我可以看到类似的行，

<dependency org="com.google.android.gms" name="play-services-maps" rev="16.0.0" transitive="false" conf="releaseCompileClasspath-&gt;default"/>

这可能是导致问题的原因吗？
