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

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