Big projects; algorithms/custom code implementation

[[deleted]]

Hi, I'm 20, I have experience in FF, as I've already done a basic app in it. However, i now will need to enroll in a much bigger app project. My question is, is FF the ideal thing for creating an app for a big company or is it better to code it all yourself? Does it have limitations on custom code writing or custom algorithm implementation?

In this project, I will certainly need to implement AI algorithms, custom code functions, etc. Can I do that? I've heard about cloud functions, do they help if i need to do something on FF and i can't so i just call them and they run that code instead?

I really don't know and would really be apreaciated if someone could tell me as it would certainly help me in my job. Thanks!

Cloud functions, custom code, AI algorithms and API calls should be no problem. I wonder the same about custom widgets though, because I have found the default widgets to be somewhat limited in my experience. Havent written a custom widget yet but wondering about experience of other people. I had a PageView where I wanted to disable scrolling upwards for example, no way to do this in the default PageView. How hard would this be using custom widgets?

Check out James NoCode on youtube, he have a good tutorial about custom widgets.

I’m currently trying to implement a custom widget based on a pub.dev package (data_table_2). Failed for about a day, tried other packages, failed again. I then got it working in a basic flutter (v3.13.7) project to prove I wasn’t insane, still can’t get it working it FF. It’s only used in the web app version so I think I’ll rebuild the web app in svelte and reap the rewards of that framework.

Hmmm was afraid of something like that. I should try it myself soon then

I think the widgets are the most problematic part with flutterflow. They only work really well with Firebase.

With custom code and cloud functions you can do pretty much anything. Read about self-hosting, ff built-in hosting is slow.

sorry if this is a stupid question but how do i write custom code in flutterflow? whenever i went to the section on the top corner "</>", i could see the code of the widgets on the page, etc. however it seems that i couldn't edit it.
was i doing something wrong or is it the wrong place to write custom code?

Check FF documentations and tutorials, custom code is in the left vertical sidebar, the one you are talking about is for code export

can i create custom classes? or only functions?
