Posting from Dart to a URL with a redirect: Since Dart's stock http package (and even the dio package) chose to handle redirects differently than basically every other language+package out there and disregard redirect responses returned to a POST request you have to do a little extra work. Worse than anything is every solution I have found was #doingItWrong and making the followup request a POST request complete with sending the payload each time. Even those approaches fail to successfully POST to a google app script (GAS). All of this is quite ironic since Dart is itself a product of Google. This is a simple proof of concept and only supports one redirect which all that is needed for a GAS doPost endpoint, but could be modified easily to accomodate other situations.
