MissingPluginException(No implementation found for method promptPermissions on channel wifi_flutter)

Hi,

I have followed the instruction to install the plugin. When I was running the example code in my flutter project, the app bar was shown successfully. Then when I clicked on the button, nothing happened and this error showed in my terminal:

Solved by disconnecting and restart the app on the phone
