FLET: Developing Flutter Apps With Python

FLET: Developing Flutter Apps With Python

FLET is one of the unique and most advanced frameworks suitable for adding the Server-Driven UI or SDUI in the Flutter app. These are also the perfect options for building standalone web or even mobile apps using the Flutter UI. 

Hiring the Flutter app development company lets you easily add the interactive widget for your Flutter app. These contents are completely controlled with the remote Python script assuring better management.

What Is FLET?

Normally, the FLET is the advanced Python Library in which the developers can easily build real-time web apps, desktop apps as well as mobile apps. There is no need to use Flutter directly to easily gain better stability.

Building the apps with Flutter also lets the developers extensively save more time in the process. Normally, the developers are required to have knowledge of the Dart language for building the app. 

But, Developers can extensively introduce the FLET module using Python codes. These especially have an extensive way of building Apps, which works perfectly for building apps in Flutter.

Required Modules:

Choosing the FLET is one of the ideal options for easily building the frequently changing and non-core changing functionality. 

These include the:

  • Product Catalogue
  • Feedback form
  • Support chat
  • In-app survey

FLET enables the team to extensively ship new features faster by easily reducing the number of App Store validation. You can simply redeploy the web app hosting a complete Python script. 

These also allow the user to easily get amazing updates to the extent. FLET provides easy-to-learn attributes on the server side. It also enables the developers to build the app even without Flutter knowledge.

Features Of FLET:

The FLET allows the developers to build unique real-time mobile, web, and desktop apps on Python. It is specially packed with a massive number of features that are suitable for developers to gain better flutter app development. Developers can easily rely on the Progressive Web App, allowing more features. These also extensively save more time in the process.

  • Powered by flutter
  • Simple architecture
  • It brings the app to life in a few minutes
  • Support features
  • Easy to Build a simple application with FLET

How To Build A Simple Application With FLET?

Apart from Python, there are lots of languages such as Go, C#, and many others available. These are significant options for easily building simple applications with the FLET.

Some of the examples are Counter applications with the:  

  • One Text-field
  • Increment & Decrement with Two buttons

Importing the FLET along with other features is quite essential for Counter App, such as the widgets. The main function is the root of the application, so they are set with the title as

The def main(page: Page):

page.title = “Counter App”

page.vertical_alignment = “center”

Text Field and Buttons



TextField(text_align=”center”,value=”0″, width=100)



alignment= “center”)


These are defined with 2 different functions so they handle the complete press events in a unique manner. Python app development is a much more simple process with the FLET methodology. These also align its features to the maximum attributes. Increment and decrement features are helpful for developing flutter apps.


def minus(e) :

tf.value = int(tf.value) -1


def plus(e) :

tf.value = int(tf.value) + 1


Simple Architecture:

Developing Flutter Apps with Python does not involve any kind of complex architecture. These are quite different from the JavaScript front-end, REST API backend, database, cache, or REST API backend. The FLET allows extensive writing of the monolith app on Python. It enables multi-user and real-time Single-Page Applications (SPA).

Powered By Flutter:

FLET UI involves building the app with Flutter. These allow the app to look professional, so it will deliver to any platform. FLET simplifies with the unique Flutter model by extensively combining the widget. It involves the complete easy-to-use controls suitable for the imperative programming model.

Quick Hosting:

Normally, it is quite important to have a text editor or favorite IDE for developing the FLET. There is no need to have complex tooling or thousands of dependencies. You can simply use the FLET to easily make the built-in web server. This lets you have quick asset hosting along with a better way of managing them.

Build Flutter Apps In Python:

FLET is one of the faster ways to easily build the Flutter app in Python. ‘tf’ involves the text field, which is replaced in the row. It also involves the text-field value for easily wrapping the value with the variables. FLET enables Python app development company to build real-time web apps. There is no need to have the front-end experience required.

Saving Your Time:

FLET is one of the ideal frameworks for easily hacking amazing-looking interactive apps. These are quite a perfect option for the dashboard or even an internal tool for the team. 

It includes several features, such as:

  • Data entry form
  • Weekend project
  • Kiosk app
  • High-fidelity prototype

Deliver To Any Device:

Deploying the flet app as a web app is a much more significant option. Users can also view it in a browser. The package involves the complete standalone desktop app for macOS, Windows, and Linux. It is the best option for installing on mobile with PWA and allows the view through the FLET app on Android and iOS.


FLET involves agnostic language, so any individual can easily develop the FLET apps in their favorite language. Normally, Python involves better supportive features for the Go, C# as well as another language to excellence.

Running The Program:

Developing flutter apps with Python is a simple process that uses the traditional method such as <file_name.py>. These play an amazing option in running the FLET files. One of the biggest problems is about making changes in the code execution. Rerunning them is easier, so the FLET gives better stability with Python while choosing for application developments.


For example, when the file is not present in the directory, then it is important to have filename.py for providing full path + filename, py. It is quite important to change the theme of the app based on the requirements.

How To Add Text To Our App?

There are various methods involved in adding text to the app. TextField is one of the best ways to add widgets or others for adding with the app. These are helpful for keeping everything updated with codes.

importflet as flt

defmyapp(page: flt.Page):

page.theme_mode = flt.ThemeMode.LIGHT

page.window_height = 400

page.window_width = 500

text = flt.TextField(

label= “Introductory Text”,

value= “This App is made using Flet.”    )


page.title = ‘GeeksApp using Flet’
