Gyroscope - Flet

Gyroscope Service

Streams gyroscope readings, reporting device rotation rate around each axis in rad/s.

**Platform Support:**

Android

iOS

Web (ignores requested sampling intervals)

**Inheritance:**

Inherits from Service.

**Properties:**

cancel_on_error: bool - If True, cancels the stream subscription on the first sensor error. Defaults to True.

enabled: bool - If True, the sensor is sampled. Set to False to stop streaming. Defaults to True.

interval: Duration | None - Desired sampling interval. Defaults to 200ms.

**Events:**

on_error: EventHandler[SensorErrorEvent] | None - Fired when the platform reports a sensor error. The event object contains an message string.

on_reading: EventHandler[GyroscopeReadingEvent] | None - Fires when a new reading is available. The event object contains x, y, z (rotation rates in rad/s) and timestamp (microseconds since epoch).

**Example Usage:**

import flet as ft
def main(page: ft.Page):
    def handle_reading(e: ft.GyroscopeReadingEvent):
        reading.value = f"x={e.x:.2f} rad/s, y={e.y:.2f} rad/s, z={e.z:.2f} rad/s"
        page.update()
    def handle_error(e: ft.SensorErrorEvent):
        page.add(ft.Text(f"Gyroscope error: {e.message}"))
    page.services.append(
        ft.Gyroscope(
            on_reading=handle_reading,
            on_error=handle_error,
            interval=ft.Duration(milliseconds=100),
        )
    )
    page.add(
        ft.Text("Rotate your device to see gyroscope readings."),
        reading := ft.Text("Waiting for data..."),
    )ft.run(main)
