I would like to know if it's possible to detect shake event with Expo ?

推荐答案

您可以使用

You can use DeviceMotion and adding a event listener for rotationRate.

rotationRate(对象)-具有对象的设备围绕对象的每个轴的旋转速率，其中包含alpha，beta，gamma键，其中alpha围绕Z轴，beta代表X轴，γ代表Y轴.

rotationRate (object) -- Rotation rates of the device around each of its axes as an object with alpha, beta, gamma keys where alpha is around Z axis, beta for X axis and gamma for Y axis.

使用此功能，您还可以查看用户旋转电话的轴(也许您希望根据摇动方向采取不同的操作).

With this you can also look in what axis the user is rotating the phone (maybe you want different actions depending on the shake direction).
