Getting "Error running Gradle" in step "resolving dependancies" when I try to execute a flutter project

Question

I suspect the proxy setting is not set correctly, or I might be wrong, please help me out here. I'm working under a corporate network and using a VPN.

Error details below:

Launching lib\main.dart on Android SDK built for x86 in debug mode...
Initializing gradle...
Resolving dependencies...
* Error running Gradle:

Finally finally figured out what I was missing, I had to set the Proxy in gradle.properties file as directed in developers.android.com. For some reason, setting up the proxy in Android Studio alone didn't work.

Updated gradle.properties file:

org.gradle.jvmargs=-Xmx1536M
systemProp.https.proxyHost=proxy.company.com
systemProp.https.proxyPort=80

PS: Thanks @Taio for your efforts. I appreciate them

Check your internet connection and make sure it is stable. Gradle is trying to connect to the internet to get resources and is unable to. In this case I would suggest turning off the vpn and waiting for the build process to go on with a normal internet connection then after build you can continue using the vpn

I can download the files when I try to access them from the browser. Should I configure proxy for Git or something? Like I have already mentioned I'm running behind a corporate network with VPN

What IDE are you using

RandomUser Over a year ago

I'm using Android studio and the proxy setting is set to auto detect. I tried setting it manually as well but didn't work.

How did the error come up. Had you done a successful build before and had you been on this same network

You have never done a successful build of a flutter app while on the network?
