How to make a food delivery application made with flutter to be modular archetictur
<extra_id_1>Assistant
To make your food delivery application more modular, you could break it down into smaller, reusable modules.

Can you give me an example 
<extra_id_1>Assistant
Sure, here’s one way you might modularize your app:
 

 - A login module, which handles authentication and authorization.
 

 - A menu module, which displays the available food choices.
 

 - A shopping cart module, which keeps track of user’s selections.
 

 - A checkout module, which handles payment and order confirmation.

How can these modules communicate with each other? 
<extra_id_1>Assistant
You can use various methods of inter-module communication. You could use a message passing mechanism, like a pub/sub bus or a simple channel. Or you could use a shared state, like a database or a cache. Or you could use a remote procedure call (RPC) mechanism, where one module “calls” a method on another module.

Can u give an example to cart module communicating with order module for sharing the product items using all communicating methods mentioned 
<extra_id_1>Assistant
Here are a few examples:
 

 - A message passing mechanism: The shopping cart module emits a “cart updated” event, which the order module listens for. The order module then updates its own state based on the cart contents.
 

 - A shared state: The shopping cart module stores its items in a database, which the order module can access. The order module then updates its own state based on the cart contents.
 

 - A remote procedure call: The shopping cart module exposes a “get items” method, which the order module calls. The order module then updates its own state based on the cart contents.

You could also break down your modules further, into even smaller modules. For example, you could have a “product details” module that displays the details of each product, and a “product add to cart” module that lets the user add products to the cart. You could also have a “basket summary” module that displays a summary of the contents of the cart, and a “checkout” module that lets the user pay for their order.
