appBuildNumber top-level constant

String? const appBuildNumber

The build number this application was built with.

This is the part of the version field in the app's pubspec.yaml after the + separator (for example 45 for version: 1.2.3+45), or the value of the --build-number option if it was provided at build time.

This will be null if the version has no build number and no --build-number option was provided.

Implementation

const String? appBuildNumber = bool.hasEnvironment('FLUTTER_BUILD_NUMBER')
    ? String.fromEnvironment('FLUTTER_BUILD_NUMBER')
    : null;
