I can't get to access document list from appwrite functions in dart

I'm absolutely new to appwrite and flutter and dart, I quite literally started playing with appwrite today a few hours ago and flutter and dart a month or so ago.

I'm trying to make a function that read and write the database based on some external server calls. I added some boilerplate documents in the database for testing purposes and started writing the logic.

I was initially trying to do some query but kept getting a blank response so I removed the query and most of the logic and kept this very simple test code but it also return nothing from the database, I'm not sure if there's something very obviously wrong in the code below that can cause this that I don't catch.

In the picture is the whole code as long as the response I keep getting.

I'm not sure how to properly debug this issue, my main point of interest is about how to verify that the function actually talk to the API, What I have tried :

• Initially, the project id and key were set in environment variables, I instead copied them directly and pasted them as strings directly into the code.
• Similarly, I wrote databaseId and collectionId directly as strings for testing purposes
• I double checked them multiple times to verify there was no mixup.

Please, can anyone help?

Also, to add to this:

• the API key was initially scopped to document read and write only but I then have it full access to everything, including database read and write but that didn't change anything as well.
• Permission for read & write are given to any for the collection I'm trying to access

Neither of which solve the issue
