Ionic vs Flutter
Ionic and Flutter are two technologies for building cross-platform apps. But that's where the similarities end. Let's explore how Ionic's standard web-based approach contrasts with Flutter's custom approach.
Since Flutter 1.0 was released in late 2018, many have asked how Ionic compares and which approach is best for them. To help developers and teams make the right decision, we put this brief comparison guide together to explain the similarities and differences. In particular, we’ll talk about the fact that, despite Ionic and Flutter sharing a similar mission and vision, our ideas abouthowhg0088线上网址 to do it could not be more different.
Of course we’re slightly biased in our outlook, but we’ve tried to keep this comparison as fact-based and balanced as possible.TL;DR
hg0088线上网址One of the things that developers often rave about with Flutter is the performance. This seems to be where all of the proprietary, non-standard stuff that they’ve invested in has paid off, and we’d agree that it sure does make for some snazzy demos.hg0088线上网址There are a few things to consider here:First, if you’re looking to do aggressive animations, Flutter might be a better fit. Then again, you might want to just go directly to the native SDKs for that matter. However, in many cases Ionic will give you the same performance if you’re writing for a more standard consumer app or employee-facing use case. The best thing to do is to build sample apps on both platforms that aligns with your use case, and see how they compare. Just keep in mind, performance almost always comes down tohow you write your codehg0088线上网址, not which platform or framework you choose.
Second, pay attention to bundle size, which will have a big impact when you deliver your app over the web. As noted above, Ionic uses the standard browser runtime and primitives, so the app size is usually very small (see a recentTODO app we built with pure web components usingStencil One, shipping at 2,991bytes). Flutter requires a huge amount of code for very basic apps (1MB for the NYT demo they shipped), because you're shipping all of that runtime even though the browser already has primitives available for almost all of it. Thus, if you’re looking to reach Google’s performance standards for Progressive Web Apps (PWAs) or to rank highly in search-engine results pages, you will find it nearly impossible with the current performance benchmarks for Flutter on web.Code portability
When it comes to deploying your app across mobile and desktop, both Ionic and Flutter appear evenly matched. Flutter’s early demos show that you can create some great looking iOS and Android apps from a single codebase. And while their desktop support is still in technical preview, the demos we’ve seen show that you can compile your app to run natively on a number of desktop platforms.The question is whether you want to deploy your app over the web, either as a traditional desktop web app or a PWA. The inherent limitations of Flutter’s web implementation (expanded upon in the Performance section above) will likely never work for apps that require fast load times and snappy performance — not to mention that their highly proprietary approach will limit the number of web libraries you can take advantage of. Given that Ionic is built on the web and based entirely on web standards, we think it’s fair to give Ionic the advantage when it comes to the targeting mobile, desktop,and the web.Native look & feel
For the most part, Flutter and Ionic will both appear native as far as the user is concerned.hg0088线上网址Although neither framework uses the native UI elements of each platform, Flutter and Ionic automatically update the design of their UI elements to match the platform that the app is running on — Material Design for Android, and Cupertino for iOS.Both solutions allow you to access platform services and native APIs through a library of pre-built plugins, along with a set of tools for building your own custom plugins as needed.However, it should be noted that Flutter’s native mobile implementation is highly opinionated. If you’re doing custom native work with Flutter, you’ll need to learn Flutter’s way of working with iOS and Android. That’s a good segue to the next top - knowledge and skillset.Knowledge and skillset
The last thing to consider is the shelf-life of your project, and the freedom and flexibility that you’ll have as your app matures.For Flutter developers, you’re putting all of your eggs in the Flutter basket, meaning if Googlekills the project (they never do that though, right?), you’ll be left with a skillset and codebase that are effectively homeless.With Ionic, you’re betting on the web, so that even if you choose to build on other platforms in the future, everything you build will still be based on open web standards. And, because Ionic relies on Web Components, you can use it with any JS framework. That’s important, because while React and Vue are hot today, that could change tomorrow. And with Ionic you’ll have the freedom to take advantage of whatever tomorrow brings.Comparison Charthg0088线上网址To help summarize the key distinctions between Flutter and Ionic, here’s a comparison chart that provides a breakdown along some of the key dimensions you’ll want to consider.
