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 ⚡️.

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 condition, allowing to recheck for updates.
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.

Dialogs
