Geolocation demo

A minimal Dioxus application that implements a native plugin.

The plugin demonstrated here makes it possible to access the user's geolocation. It does a few things:

• Inspect and request location permissions using the native Android/iOS dialogs.
• Configure one-shot position requests (high-accuracy toggle + maximum cached age).
• Inspect the last reported coordinates, accuracy, altitude, heading, and speed.

The example shares the same metadata pipeline as any plugin crate: the native Gradle/Swift artifacts are embedded via linker symbols and bundled automatically by dx.

Running the example

# Inside the repository root
dx serve --project examples/01-app-demos/geolocation --platform mobile

For Android/iOS you’ll need the respective toolchains installed (Android SDK/NDK, Xcode) so the geolocation crate’s build.rs can build the native modules. The UI also works on desktop/web, but location calls will return an error because the plugin only supports mobile targets—those errors are shown inline in the demo.

Things to try

1. Tap Check permissions to see the current OS state (granted/denied/prompt).
2. Tap Request permissions to trigger the native dialog from within the app.
3. Toggle High accuracy and set a Max cached age before requesting the current position.
4. Observe the coordinate grid update whenever a new reading arrives, or the error banner if the operation fails (e.g., permissions denied or running on an unsupported platform).
