Flutter VS kivy

Flutter is a popular hybrid mobile app framework developed by Google. It allows developers to build cross-platform applications using a single codebase written in Dart. Unlike many frameworks, Flutter uses its own rendering engine to draw UI components, ensuring consistent design and performance across devices. This approach delivers near-native performance and highly customizable user interfaces. With features like hot reload and a rich widget library, Flutter is widely used for building fast, visually appealing, and scalable mobile applications.

# Inside Ubuntu proot apt update && apt install -y curl git unzip xz-utils zip openjdk-17-jdk # Clone Flutter (ARM64 compatible) cd /root git clone https://github.com/flutter/flutter.git -b stable --depth 1 export PATH=/root/flutter/bin:$PATH # Let Dart figure itself out flutter precache --linux flutter doctor

Not all semantic properties work the same way across platforms. Some platforms support certain properties. Others might behave differently. For example, headingLevel only works on Flutter web. Native iOS supports heading levels. Flutter doesn’t wire this through on iOS (there’s an open issue in the Flutter tracker). Android doesn’t even have the concept of heading levels.

Flutter offers an alternative approach when we need truly native performance or access to device-specific features that web APIs don't expose. The Dart language provides strong typing similar to TypeScript, and the framework renders using native components rather than WebView. For AI applications, Flutter's isolates handle background processing without blocking the UI, essential when you're running lighter ML models on-device for offline functionality.

Flutter : Obviously 😂

With the app market projected to reach over $500 billion by 2025, integrating AI isn't just advantageous—it's essential for staying competitive. Whether you're building a mobile app for education, a web platform for e-commerce, or an enterprise tool for data analysis, AI can accelerate development cycles, reduce costs, and enhance functionality. However, effectiveness depends on context: the app's purpose, your team's expertise, and scalability requirements. As we navigate this topic, remember that the "best" tool often involves combining several for optimal results.

There are more than 10 built-in ways to find the widgets. On this article Only the most reliable and used will be shown, but, if you want to see all of them, check them here.

Because I mainly work with python, I am using Kivy (https://kivy.org/).

Earlier I was HTMX, Jinja templates, Flask, Tailwind and little vanilla JS. It was too inelegant for my taste.

I am considering moving to either Swift, or JS/Svelete

There are some things available, and people are working on it. Coincidentally, one of those people is Russell Keith-Magee of Django fame, who founded the BeeWare project.

Could someone fix the Kivy build with GCC 14?

> https://github.com/kivy/kivy/issues/8557

This issue has been unresolved for half a year now.

We will create this complete Python registration form using Kivy. We get started by installing Kivy, a powerful Python framework for building interactive applications.

For reference, YouTube runs on Python[1,2,3]:

> 1. Python and Django: YouTube’s backend is predominantly written in Python, offering a balance of performance and readability.

> 2. Google Cloud Platform...

> 3. Java and C++: YouTube also utilizes Java and C++ for specific backend services, as they provide better performance for certain tasks.

A long time ago, I looked into these Python frameworks:

I have a multi-threaded app using Kivy for the GUI and sometimes need to update the GUI from a background thread. This app is a few years old and I recently updated to Kivy 2.2 and am now getting an exception with the message "Cannot create graphics instruction outside the main Kivy thread" -- which is related to this change in Kivy 2.1: https://github.com/kivy/kivy/pull/7270

I suggest you use kivy which is suitable for the desktop but also has the advantage of being one of few options for creating Python based native(ish) mobile apps (for IoS and Android app stores).

I think the best one right now for python is "beeware": https://beeware.org/

You also have Kivy which is prety good: https://kivy.org/
