In the rapidly advancing world of mobile app development, Flutter has gained widespread recognition for its cross-platform development capabilities. Building an app that runs smoothly on Android and iOS platforms is no longer a dream. However, what if you discover a significant bug after releasing your Flutter app on various platforms or decide to unveil a new feature to enhance user experience? Here's where the concept of Flutter Code Push comes into play. It gives developers the power to push app updates directly to users' devices, thus revolutionizing how we handle updates and making it a game changer in mobile app development.
Flutter Code Push is a technology that allows developers to push live updates to a production application without going through the standard lengthy process of updating via the App Store or Google Play. This is beneficial for introducing new features, quick bug fixes, and updates without all the hassle.
This technology, adopted by Flutter, also benefits the users, as they get immediate updates, enhancements, and fixes, ultimately improving the user experience significantly. Flutter Code Push signifies an evolution in the realm of app updates, reducing the gap between the developers and the users.
As we dive deep into the subject, it's essential to understand what constitutes a code push for Flutter. The key idea is to use a cloud service that pushes the changes in code directly to the user's devices, eliminating the need for users to manually update the app from the App Store or Google Play Store.
Here’s a simplified overview: developers use a Shorebird account to create a release of the changes. This release, a new feature, bug fixes, or UI alterations, is pushed to the Shorebird servers. Subsequently, the updated version of the app is downloaded to the users' devices when they open the app — a process known as over-the-air updates.
It's worth noting that the native code cannot be updated using this technique. So, significant changes that require alterations at the native level would need a proper update via the app stores.
This technique has already been used in production apps as well. LinkedIn, for instance, has a notable architecture lead in implementing over-the-air updates using the Shorebird servers.
Why does Chimera Flutter code push exist, and how does it stand out? Chimera, an implementation of Flutter Hot Code Push, allows over-the-air updates on existing apps built in Flutter. It's especially invaluable when a quick solution is needed, possibly as an emergency fix for malfunctioning or updating new features.
It creates a Shorebird release, which sends the updates to the Shorebird servers. These are then directly reflected on users' devices when they open the app, regardless of whether they are on Apple's App Store or Google Play, as Chimera supports Android and iOS.
With its astonishing convenience to 'push app updates directly,' it's no surprise that Chimera Flutter Code Push is a popular choice among mobile app developers.
The functionality of Flutter Hot Code Push is deeply tied with the Flutter engine, which in applications, is bundled together with a specific version of the Dart SDK. The process involves the runtime obtaining the newer Dart code over the network and replacing the older versions with the new one.
Unlike the traditional way of releasing app updates, with hot code push, there's no need to rebuild or redeploy the entire app. Instead, new patches can be immediately reflected on users' devices, fostering a smoother update experience for developers to push app updates and the users receiving them.
Developers can trigger Shorebird Updater to check for updates, download them, and apply them as needed. Ensure to initialize Shorebird in the main() function and check for updates before running the app.
With the Dart code push capability, the Flutter engine combines the new Dart code with the existing native code to produce an updated functional app.
Leveraging Shorebird Code Push in your Flutter project can be an enriching experience. With extensive documentation and an active community of Flutter developers, getting started with Shorebird is straightforward.
To use Shorebird's capabilities, you must create a Shorebird account, subscribe to a paid account for their cloud service, and install the Shorebird CLI on your computer. Instructions for these can be found on the official Shorebird website.
After setting up your Shorebird account, use the Shorebird CLI to release a Shorebird patch for your application. This patch contains the new code for your app and is uploaded to the Shorebird servers using the shorebird release command.
Once the new patch is live on the Shorebird servers, you can use the Shorebird library in your Flutter application to initialize Shorebird and apply the new patch. This results in your application being updated directly on the users' devices, effective the next time the app is opened.
Shorebird has revolutionized how we push app updates directly, making it an essential tool for every Flutter developer.
Central to the process of Flutter code push is Dart Code. Dart is the programming language used in Flutter app development, and its architecture allows for hot code push functionality to be implemented efficiently.
Hot Code Push keeps the app's native code the same while replacing the existing applications' Dart bytecode on the fly. This is possible because the Flutter engine runs on the Dart virtual machine (VM), which allows the app's behavior to be modified at runtime using the new Dart code.
Developers create a Shorebird patch containing the updated code to update the Dart Code. This patch is then uploaded to the Shorebird servers, delivered as over-the-air updates to the users. The users do not need to fetch the update, making the process seamless manually.
One of the unique capabilities of Shorebird and Flutter code push is the ability to push app updates directly to the users' devices without going through the traditional app update cycle via Google Play or the App Store. This means you can roll out new features, make bug fixes, or tweak your app's UI, delivering updates directly to the users' devices. Imagine pushing your newly polished feature to users quickly, skipping the wait for store approvals!
But what does it mean for your end-users? A seamless, uninterrupted service with real-time access to new features and fixes. It eliminates the need for them to continuously check their App Store or Google Play Store for updates. Instead of manually updating it, users get the latest version of their favorite apps whenever they open them, enhancing their overall app usage experience.
While Flutter Code Push does reinvent the wheel regarding app updates, there are a few hurdles developers should be aware of.
Notably, Flutter Code Push is only applicable for pushing changes related to the Dart Code, not for changes in the native code. If your update also includes alterations to the native code, you might still have to resort to the traditional process of pushing updates via the App Store and Google Play Store.
Furthermore, implementing over-the-air updates requires compliance with the terms of service from Apple's App Store and Google Play Store. Creators must ensure their updates remain the same as the app's initial purpose as submitted for review.
Despite its limitations, the Flutter Code Push technique is still beneficial for pushing minor updates, bug fixes, and feature enhancements.
In the landscape of mobile app development, the power to push app updates directly is an absolute game-changer. With the technology of Flutter Code Push utilizing the Shorebird platform, developers can swiftly roll out modifications, thereby improving app usability for the end-users.
Whether bug fixes, feature enhancements, or emergency fixes - Flutter Code Push ensures an expedited, efficient update process. While it has its limitations, its advantages to both developers and users make it an essential tool in app deployment and maintenance.
Keep pushing codes; keep delighting users! The future is here, and it continues to emerge with tools like Flutter and Shorebird that rewrite the game's rules. Happy coding!
