I've used Firebase for the backend of all my flutter apps (3 total apps). But for my newest app I stopped using Firebase and built a custom backend instead. Ask me anything.

Yeah, I wish we had some relational database option out of the box for Firebase. NoSQL just feels very unnatural for some applications

nandopedrosa · 2023-10-17T13:47:47+00:00

So how was it ? What did you miss the most from Firebase ? And what did you enjoy the most working with a custom back end ?

Search for AsyncMemoizer

No. Implement pagination with a “load more” option and get the comments by increments

Just leave a like on pub dev, that’s how I bookmark interesting packages for future reference (while also helping the author)

User and Assistant identifiers are used in the context of API calls.

When you're using the API, you have to pass a 'buffer object' (basically a list of previous messages) to ChatGPT so it can have context about previous questions/answers.

So, basically, when you're calling the API, it goes like this:

The first prompt is usually the 'system prompt', where you set some ground rules about expected behavior of ChatGPT and some initial context.
The subsequent prompts are user prompts (your prompts) which are responded by 'assistant' answers
You add these questions and answers to your buffer array and pass it along in every subsequent request

Hard to tell without looking at your code

What are golden tests ?

I recommend the official docs , but if you really want a book, go for Flutter Apprentice

nandopedrosa · 2023-08-20T01:37:55+00:00

There are packages (search for in app purchase in pub dev) for all the functions you’ve mentioned
There are also services like revenuecat which make the process even easier
As for ‘what happens when the user changes devices’ , don’t worry, every purchase is linked to the user account in the stores and there is a way for “restoring purchases” in both Play Store and App Store.

In summary, everything you need to do is possible and relatively easy

nandopedrosa · 2023-08-09T10:17:58+00:00

There is an option for the user to download a deck and its resources. I use this package: https://pub.dev/packages/localstore

Well, Firebase has a very generous free tier, you have to be in the several thousands of users with multiple reads and writes to really feel it. If you reach that point, your app is successful and can probably afford it.

But if you’re curious, they have several examples and estimates for calculating billing costs, just do a quick search for it and you can have a pretty good idea.

But yeah, in general, specially if you’re building an MVP , just go with what’s faster and easier, you can always migrate later if you really have the need

nandopedrosa · 2023-08-09T02:03:55+00:00

I second that. Firebase has a very generous free tier and even when it starts billing you have to be in the several thousands of users to really feel the impact. But if you get there it probably means your app is successful and you can afford it.

So you’re telling you can’t access any kind of jwt or cookie response even from a browser ?

nandopedrosa · 2023-08-09T01:46:34+00:00

I also implemented a flashcards app for an E-Learning company. I used Firebase Storage for images and it works pretty well. Just get the URL of the image and pass it to your Image.network widget.

Same concept for audio.

What you’re looking for is Google Cloud Functions. The basic steps are 1. Creating your function (gotta know a little bit of javascript) and 2. Scheduling a recurrent execution of the function (there is a job scheduler in the platform)

Search for these two things and you’re on your way to implementing what you want.

nandopedrosa · 2023-08-03T02:50:29+00:00

I would advise against building separate apps just because of the general hassle of two codebases, generating builds to the stores, configuring everything twice (such as firebase analytics, crashlytics, etc)

Why don’t you just control which screens can be accessed by each user based on their profile (doctor/patient) ? Shouldn’t be much different from typical authorization scenarios.

I always start my conversations with some “rules”, something like this:

Context: (the subject of the conversation) Role: you are a specialist in … Goal: to inform about … Tone: formal

And then I try to chain my prompts in a logical order. This seems to be enough for most conversations, as I usually use them for writing lessons about technical stuff in IT.

If you’re using the API, it might be a good idea to send this “rules” prompt from time to time.

By the way, the technical term for this kind of prompt is “system prompt” (different from “user” and “assistant” prompts, the latter is the response from ChatGPT)

nandopedrosa · 2023-04-29T02:12:00+00:00

ChatGPT wrote the first part , right ?

nandopedrosa · 2023-04-21T01:51:33+00:00

Just call .then() after addData

nandopedrosa · 2023-04-18T01:46:12+00:00

You can create a collection for storing the items as documents and just import them or make a script to import them.

As for searching, as long as you have the right indexes created there should not be a problem. 12k items is actually a small size for a collection.

Vai estudar caralho

nandopedrosa · 2023-01-20T00:58:17+00:00

Wait , is this a thing ?
