Answer 1

You might need to setup a self-signed certificate to make it work correctly by setting the following enviroment variables:

On Linux:

export DART_VM_OPTIONS="--root-certs-file={path.to.certificate.file}"

On Windows:

set https_proxy="--root-certs-file={path.to.certificate.file}"

Answer 2

I had the same issue. I am working in a company and I had to use https_proxy env variable to get connection.

Open cmd on Windows

set https_proxy=USERNAME:PASSWORD@hostname:port

flutter create

flutter run

flutter packages get

This worked for me, hope it helps!

Answer 3

Do this for windows environment

set https_proxy=USERNAME:PASSWORD@hostname:port
set http_proxy=USERNAME:PASSWORD@hostname:port
set NO_PROXY=localhost,127.0.0.1

before calling flutter create <flutter_project>

Answer 4

I was successful after setting the following windows environment variable.

Variable name: DART_VM_OPTIONS Variable value: --root-certs-file=path_to_cert

Where path_to_cert is the fully qualified path.
