With the help of Pietro during his minutes of free time for advice, and Agon#3773 from the r/FlutterDev Discord community, we found a solution within the week! And we’re moving forward on all fronts!
Agon (@noga_dev) was kind enough to help me (Sabian) realize where the problem was coming from, saving loads of time in finding the root of the issue, and Pietro who continues to be an awesome dude helped me track down files I had been missing which were crucial to solving the API issue.
Thank you for your help!
Now, let’s do this.
