Updat - The simple-to-use, flutter-based desktop update package #

Updat is a simple-to-use reliable flutter-native updater that handles your application's updates. All you need is a place to host your files and a place to check for the latest version.

Demo #

Installing #
To get started simply type flutter pub add updat in your terminal.
🎉 Done, It's that simple.
Getting Started #
Integration with your app requires just a few lines of code, add the following widget wherever you want your updat widget to be:
UpdatWidget(
currentVersion: "1.0.0",
getLatestVersion: () async {
// Here you should fetch the latest version. It must be semantic versioning for update detection to work properly.
return "1.0.1";
},
getBinaryUrl: (latestVersion) async {
// Here you provide the link to the binary the user should download. Make sure it is the correct one for the platform!
return "https://github.com/latest/release/bin.exe";
},
// Lastly, enter your app name so we know what to call your files.
appName: "Updat Example",
),

That should get you up and running in just a few seconds ⚡️.
or use the UpdatWindowManager, and let updat handle everything on autopilot. Just place it right after your MaterialApp.

Theming #

Updat is extremely easy to theme. We also use updateChipBuilder and updateDialogBuilder internally to design our widgets, so you have the same customizability we do. We provide a couple of themes to get you started.
To change the theme simply add the desired theme to the builder and you're set.
Chips

defaultChip which is an elevatedButton that only shows when an update is available. Shown by default.

defaultChipWithCheckFor which is an elevatedButton that shows under all conditions, allowing to recheck for updates.

defaultChipWithSilentDownload which is an elevatedButton that only shows when an update is downloaded and ready to install.

flatChip which is an textButton that only shows when an update is available

flatChipWithCheckFor which is an textButton that shows under all condition, allowing to recheck for updates.

flatChipWithSilentDownload which is an textButton that only shows when an update is downloaded and ready to install.

floatingExtendedChip which is a compact version of the dialog, which is a bit bigger and grabs user's attention more easily.

floatingExtendedChipWithSilentDownload which is a compact version of the dialog, which is a bit bigger and grabs user's attention more easily, and only shows when the update is ready to be installed.

Dialogs

defaultDialog which is the default, M2 and M3 dialog that shows by default.

Advanced Usage #
If you need to send additional HTTP headers when downloading a release asset, you may define your
headers by setting the downloadReleaseHeaders property of UpdatGlobalOptions, you should probably do this in the main function of your code.
UpdatGlobalOptions.downloadReleaseHeaders = {
"Authorization": "Bearer gh_pat_1234567889abcdefghijklm",
}
