Firebase vs. Flutter by Google

Firebase should be your first choice if your platform is mobile first. Firebase's mobile platform support for client-side applications is second to none, and I cannot think of a comparable cross-platform toolkit. Firebase also integrates well with your server-side solution, meaning that you can plug Firebase into your existing app architecture with minimal effort.

Firebase lags behind on the desktop, however. Although macOS support is rapidly catching up, full Windows support is a glaring omission for most Firebase features. This means that if your platform targets Windows, you will need to implement the client functionality manually using Firebase's web APIs and wrappers, or look for another solution.

Flutter is well known for native app development, if you have android studio installed on your system, you can quickly start using it. This might not be the best choice for you if you do not wish to learn a new language, i.e. Dart and you do not know it already.

• Extremely robust. Has about any tool you can think of under one roof making it extremely useful as a backup platform for data analytics or small teams that need something quickly.
• Intuitive and easy UI/UX. Being made and owned by Google, you expect nothing less. Very easy to use for anyone that has any marketing or analytical experience especially in Google Analytics (which I just assume all marketers do).
• Safe, secure, and sturdy. Never need to worry about downtimes or misinformation as it's as clean and safe as it is being run by Google.
• FREE! What else is there to say. Unless you're an extremely large application handling hundreds of thousands to millions of users, this pay as you go plan will stay free.

• It is powered by Google, so a great technical community is backing it.
• The development of native apps is an easy process using Flutter.
• As it is an open-source tool, we can use it without paying anything.
• It provides nice UI options.

• Firebase/Firestore has very limited support for querying more complicated items; for example, performing a simple string search is not possible.
• While upfront costs are low, costs can grow quickly if you're not careful about what you are being billed for.
• Dashboards have at times shown different information to what is billed, and support from Google is less than stellar and not as effective as that from Amazon or Microsoft.

• Occasionally updates to the Flutter SDK result in wide-sweeping changes that seem to not be thoroughly tested and considered. Flutter sometimes evolves too fast for its own good.
• While the 3rd-party Flutter package ecosystem is vast and rich, 1st-party support for basic things (audio/video playback, battery information, Bluetooth services, etc.) are lacking. You are occasionally forced to rely on an open-source package for use-cases that other platforms have native support for.
• Documentation, particularly around testing, is lacking. While there are some great docs, like the Dart Style Guide, many Flutter-focused support documents are lacking in quality and real-world usability.
• Flutter allows you to architect an app however you want. While this is a great feature, it also adds complexity and leads to the current state of Flutter's state management, where there are 50+ options on how to organize your app, with very little official guidance or recommendations from the Flutter team. For a beginner, this can create decision paralysis.

Firebase functions are more difficult to use, there are no concepts of triggers or cascading deletes without the use of Firebase functions. Firebase functions can run forever if not written correctly and cause billing nightmares. While this hasn't happened to us specifically it is a thing that happens more than one realizes.

Our analytics folks handled the majority of the communication when it came to customer service, but as far as I was aware, the support we got was pretty good. When we had an issue, we were able to reach out and get support in a timely fashion. Firebase was easy to reach and reasonably available to assist when needed.

Before using Firebase, we exclusively used self hosted database services. Using Firebase has allowed us to reduce reliance on single points of failure and systems that are difficult to scale. Additionally, Firebase is much easier to set up and use than any sort of self hosted database. This simplicity has allowed us to try features that we might not have based on the amount of work they required in the past.

I have experience with react and React Native. I would say that the idea behind all those frameworks are quite similar. However, I found the javascript-based frameworks a bit more accessible as you could utilise your javascript knowledge. Here, Flutter works with its own language. This has advantages and disadvantages sometimes. I found the community around javascript frameworks bigger and therefore sometimes more helpful. However, Flutter does a good job here as well. I think the main argument for Flutter is its usability for less experienced developers. If you do not have knowledge in javascript or other programming languages then I think it is much easier to start with Flutter than with another framework like react. I think the package that you get form scratch is better than in the other frameworks were you have to set up and learn a lot more before you can start.

• Firebase has been able to help us understand reliably, the drop-off in our user flows with their funnel feature. This has made it easy for us to be able to pinpoint weaknesses in our funnel and test and optimize with data as the dependent variable.
• From an economic standpoint, we don't pay for Firebase which is great, but as the saying goes "You get what you pay for" also holds true in this context. As we looked to grow and scale, we looked for a paid solution.
• From a developer resource standpoint, Firebase has been extremely easy to integrate into our app. Whether it be the event tracking, dynamic links or crash reporting we have not had to waste too much developer time thanks to their well-organized developer docs.

• The rapid development capabilities of Flutter allow us to build apps we could not have previously considered commercially viable, opening new revenue streams.
• Free and open licensing made adoption very easy (ie. free/low cost!).
• In comparison to Qt, our time spent arguing with build tools and perfecting development environments has decreased substantially.
