Flutter vs Onsen UI: What are the differences?

Widget Library: Flutter provides a comprehensive set of customizable widgets that follow Material Design guidelines for Android and Cupertino styling for iOS, allowing developers to create consistent and visually appealing user interfaces across platforms. On the other hand, Onsen UI offers a collection of pre-designed UI components that can be easily customized with themes but may not provide as extensive widget options as Flutter.
Languages: Flutter uses Dart as its primary programming language, offering features like Just-In-Time compilation for faster development cycles and Ahead-Of-Time compilation for optimized performance. In contrast, Onsen UI supports HTML5, CSS, and JavaScript, making it more accessible to web developers who are already familiar with these technologies but potentially limiting the performance optimizations available in Dart.
Platform Support: Flutter is known for its strong support for both Android and iOS platforms, with native-like performance and access to platform-specific features through plugins. Onsen UI, on the other hand, is primarily focused on web applications but can be used with frameworks like Cordova or PhoneGap to create hybrid mobile apps, which may not offer the same level of optimization as Flutter.
Community and Ecosystem: Flutter has a rapidly growing community and a rich ecosystem of packages, tools, and resources available through sites like pub.dev, providing developers with a wide range of options for enhancing their projects. In comparison, Onsen UI has a smaller community and fewer third-party resources, which could potentially limit the support and solutions available to developers working with the framework.
Performance: Flutter is known for its high-performance rendering engine, Flutter Engine, which offers smooth animations, fast UI updates, and efficient memory management for complex applications. Onsen UI, while capable of delivering responsive user interfaces, may not match the performance capabilities of Flutter, especially in scenarios that demand heavy computations or graphics processing.
Learning Curve: Flutter's reactive programming model, based on widgets and state management mechanisms like Provider or Bloc, may have a steeper learning curve for developers who are new to the framework or the Dart programming language. On the other hand, Onsen UI's familiarity with web technologies like HTML and CSS could make it easier for web developers to transition into mobile app development with the framework.

In Summary, Flutter and Onsen UI differ in terms of widget libraries, programming languages, platform support, community size, performance capabilities, and learning curves.

Advice on Onsen UI, Flutter

We built the first version of our app with RN and it turned out a mess in a while. A lot of bugs along with poor performance out of the box for a fairly large app. Many things, that native platform has, cannot be done with existing solutions for RN. For instance, large titles on iOS are not fully implemented in any of existing navigations libraries. Also there's painfully slow JSON bridge and many other small, yet annoying things. On the other hand Flutter became a really powerful and easy-to-use tool. A bit of a learning curve, of course, because of Dart, but it worth learning. Flutter offers TONS of built-in features, no JSON-bridge, AOT compilation for iOS.

While with Ionic it is possible to make mobile applications with only web technologies, Flutter is more performant and is easy to use if you are willing to learn Dart, which is a fun language. Plus, it has awesome documentation and, while its ecosystem isn't near as big as JavaScript's is, it has a good package manager called Pub and its packages are generally high quality.

Needs adviceon

Flutter

React Native

I am building an app that would need at least two external APIs: a map and a payment service. I am currently building in Flutter, but I am having trouble integrating one of the external APIs with the app. I wonder (because I am still at the beginning) if I should switch to React Native or build native iOS and Android apps separately. Any advice would be appreciated!

Detailed Comparison

Onsen UI	Flutter
Onsen UI helps you develop both hybrid and web apps. If developing hybrid apps, you can use it with the Cordova / PhoneGap command line, or with Monaca tools (CLI, Monaca IDE - cloud-based IDE for Cordova, Localkit - desktop GUI).	Flutter is a mobile app SDK to help developers and designers build modern mobile apps for iOS and Android.
Open source HTML5 hybrid app framework for PhoneGap & Cordova; JavaScript framework agnostic; Mobile-optimized HTML5, CSS and JavaScript with Web components; UI framework; Responsive layout; Material and Flat design; Comprehensive toolset (CLI, IDE, debugger, remote build etc.) provided as Monaca	Fast development - Flutter's "hot reload" helps you quickly and easily experiment, build UIs, add features, and fix bug faster. Experience sub-second reload times, without losing state, on emulators, simulators, and hardware for iOS and Android.;Expressive UIs - Delight your users with Flutter's built-in beautiful Material Design and Cupertino (iOS-flavor) widgets, rich motion APIs, smooth natural scrolling, and platform awareness.;Access native features and SDKs - Make your app come to life with platform APIs, 3rd party SDKs, and native code. Flutter lets you reuse your existing Java, Swift, and ObjC code, and access native features and SDKs on iOS and Android.

What are some alternatives to Onsen UI, Flutter?

Ionic

Free and open source, Ionic offers a library of mobile and desktop-optimized HTML, CSS and JS components for building highly interactive apps. Use with Angular, React, Vue, or plain JavaScript.

React Native

React Native enables you to build world-class application experiences on native platforms using a consistent developer experience based on JavaScript and React. The focus of React Native is on developer efficiency across all the platforms you care about - learn once, write anywhere. Facebook uses React Native in multiple production apps and will continue investing in React Native.

Xamarin

Xamarin’s Mono-based products enable .NET developers to use their existing code, libraries and tools (including Visual Studio*), as well as skills in .NET and the C# programming language, to create mobile applications for the industry’s most widely-used mobile devices, including Android-based smartphones and tablets, iPhone, iPad and iPod Touch.

NativeScript

NativeScript enables developers to build native apps for iOS, Android and Windows Universal while sharing the application code across the platforms. When building the application UI, developers use our libraries, which abstract the differences between the native platforms.

Apache Cordova

Apache Cordova is a set of device APIs that allow a mobile app developer to access native device function such as the camera or accelerometer from JavaScript. Combined with a UI framework such as jQuery Mobile or Dojo Mobile or Sencha Touch, this allows a smartphone app to be developed with just HTML, CSS, and JavaScript.

Framework7

It is a free and open source mobile HTML framework to develop hybrid mobile apps or web apps with iOS native look and feel. All you need to make it work is a simple HTML layout and attached framework's CSS and JS files.

Qt

Qt, a leading cross-platform application and UI framework. With Qt, you can develop applications once and deploy to leading desktop, embedded & mobile targets.

PhoneGap

PhoneGap is a web platform that exposes native mobile device apis and data to JavaScript. PhoneGap is a distribution of Apache Cordova. PhoneGap allows you to use standard web technologies such as HTML5, CSS3, and JavaScript for cross-platform development, avoiding each mobile platforms' native development language. Applications execute within wrappers targeted to each platform, and rely on standards-compliant API bindings to access each device's sensors, data, and network status.

Expo

It is a framework and a platform for universal React applications. It is a set of tools and services built around React Native and native platforms that help you develop, build, deploy, and quickly iterate on iOS, Android, and web apps.

Vue Native

Vue Native is a mobile framework to build truly native mobile app using Vue.js. Its is designed to connect React Native and Vue.js. Vue Native is a wrapper around React Native APIs, which allows you to use Vue.js and compose rich mobile User Interface.
