无法将新文物与Flutter 项目集成在一起

我试图将我的Ffltter项目与用于应用程序监控的New Relic集成在一起，但当我try 为Android平台构建该项目时，我收到以下错误:

FAILURE: Build failed with an exception.

* Where:
Build file 'C:\Projects\Flutter Projects\easy_invest_app\android\build.gradle' line: 29

* What went wrong:
A problem occurred evaluating root project 'android'.
> A problem occurred configuring project ':app'.
   > groovy.lang.MissingPropertyException: Could not get unknown property 'sources' for object of type com.android.build.api.component.analytics.AnalyticsEnabledApplicationVariant.

这是我的‘安卓/build.gradle’文件:

buildscript {
    ext.kotlin_version = '1.7.20'
    repositories {
        google()
        mavenLocal()
        mavenCentral()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:7.1.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.13'
        classpath "com.newrelic.agent.android:agent-gradle-plugin:7.1.0"
    }
}

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}

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

tasks.register("clean", Delete) {
    delete rootProject.buildDir
}

SDK的最低版本是24，我添加了this guide表示的所有内容，但仍然出现错误.我怎么才能解决这个问题呢？

我希望将新的遗迹集成到我的Android项目输出中.
