Flutter – Gradle threw an error while downloading artifacts from the network

No matter how hard I tried and looked for solutions online, none of them worked. It’s strange because my old project is running fine, but when I tried to create a new project and run a basic counter app, it kept giving me an error. It’s really frustrating when something that should be simple becomes so complicated.

I tried to change the classpath – it works in the old project!

classpath 'com.android.tools.build:gradle:7.3.0'

to

classpath 'com.android.tools.build:gradle:4.1.0'

also I tried

deleted the gradle-wrapper.jar file and run – nothing works

downgrade the distributionUrl in gradle-wrapper.properties

distributionUrl=https://services.gradle.org/distributions/gradle-7.5-all.zip

to

distributionUrl=https://services.gradle.org/distributions/gradle-7.2-all.zip
&
distributionUrl=https://services.gradle.org/distributions/gradle-6.7-all

I’m running the projects in VS-code

    I have no idea why my project running after changing some Android files!

    What I did!

    build.gradle

    ext.kotlin_version = '1.7.10'

    to

     ext.kotlin_version = '1.6.10'

    classpath 'com.android.tools.build:gradle:7.3.0'

    to

    classpath 'com.android.tools.build:gradle:4.1.0'

    buil.gradle in app folder

    android {
    namespace "com.example.image_picker"
    compileSdkVersion flutter.compileSdkVersion
    ndkVersion flutter.ndkVersion

    to

    android {
    compileSdkVersion flutter.compileSdkVersion
    ndkVersion flutter.ndkVersion

    gradle-wrapper.properties

    distributionUrl=https://services.gradle.org/distributions/gradle-7.5-all.zip

    to

    distributionUrl=https://services.gradle.org/distributions/gradle-7.4-all.zip

    every AndroidManifest.xml file

    <manifest xmlns:android="http://schemas.android.com/apk/res/android">

    to

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.flutter_profile">

    Now I can run the projects without errors but I have quite curious to know why my projects running after changing these many things

    Try using VPN.
    Connect to the VPN then run your project, it may take a while as it the first time, I would also highly recommend that you run your project on a real phone, not on emulator.
