Building a Shopping Cart with Getx, Stripe and Firebase | PART 2

[@codewithsebastian]

This is nice, but one thing I think is crucial in professional app development is, 1. You wouldn't let any changes you make from the app affect the database like that especially with firebase where every read and write counts. >>Suggestion would be transfer the cart calculations to the app and only send a completed order to the database. >> However, you may want to save the cart items in local storage to maximise the chances of the user buying that product next time they visit the app or send notification if a cart item stays in cartList for a particular period of time. Nonetheless nice video, I was looking for inspiration on how products page/ cart page should look like and this did wonders.

can we build a cart same like this without any database included??? please reply

[@SteveKeddy2009]

How can we use get_Storage to change the collection in the product_controller.dart file?

[@ryancitocoreano]

when I increase the quantity of the product, UI is not updated till I save any file on VS Code...

[@SteveKeddy2009]

Hi Santos - Great videos! I have one small problem Im struggling with. How can I change the collection string in product_controller ? Is there a way using provider to change the query string so that we can build a shopping cart with several categories? Or would shrared preferences be a viable option for this? I cant seem to find a way to manipulate this controller class. Any suggestions?

I have downloaded your source code, have created a database in firestore like you, but I can see the cards. Always get the result in debug console: E/flutter ( 6639): [ERROR:flutter/lib/ui/ui_dart_state.cc(199)] Unhandled Exception: NoSuchMethodError: Class 'String' has no instance method 'toDouble'. E/flutter ( 6639): Receiver: "18.0" E/flutter ( 6639): Tried calling: toDouble() new ProductModel.fromMap " E/flutter ( 6639): #2 "ProducsController.getAllProducts.." I dont know, where exactly could be the problem. Do you have any Idea?

[@ryancitocoreano]

I've got an error on the line 32, 34 of cart_item.dart "Unhandled Exception: NoSuchMethodError: Class 'String' has no instance method 'toDouble'." toDouble doesn't work for this case? I tried cost = double.parse(data[COST]) error message indicates between data and [COST], "data>here

[@ryancitocoreano]

Weird... I changed code to cost = double.parse(data[COST].toString()); then, it is working... ;;;

One crucial thing that is missing from this, is the shoe sizes. This app wouldn't be functional without it.

[@SantosEnoque]

Hey mate, actually the goal of this mini projecto is to build a shopping cart, imagine it as a feature pf a shopping app, so here we want tp add products to the user cart and the charge the customers using stripe

[@nalbur_]

İs that true way using cart with stream? Does it can create some errors because of network problems? We can get items from db and we can calculate price etc. Manually and we can update db. Which is common way which is ideal sir?
