How to create reusable app components in python flet tutorial

creating reusable app components in python is an essential practice for building maintainable and scalable applications. in this tutorial, we will focus on using the flet framework, which is designed for building interactive web applications with python.

### what is flet?

flet is a web framework that allows you to create interactive applications in python with minimal effort. it provides a simple api for building user interfaces and handling user interactions.

### prerequisites

- python 3.7 or higher
- basic understanding of python programming
- familiarity with web development concepts

### installation

to get started, install flet using pip:

### creating reusable components

reusable components are functions or classes that encapsulate specific functionality and can be used across different parts of your application. in this tutorial, we'll create a simple reusable button component and a text input component.

#### step 1: setting up your project

create a new directory for your project and navigate into it:

#### step 2: creating a reusable button component

in this code:
- we define a function `create_button` that takes a label and an `on_click` callback function as arguments. this function returns an `elevatedbutton` from the flet library.
- we create a simple `main` function where we define the application interface and use our reusable button component.

#### step 3: creating a reusable text input component

next, let's create a reusable text input component:

in this code:
- we define a function `create_text_input` that accepts a label and an `on_change` callback function. this function returns a `textfield` from the flet library.
- we use this text input component in the `main` function along with our button.

### step 4: running the application

to run the application, execute the following command in the terminal:
