createChannel(channel: AndroidChannel): Promise<string>;

Creates a new Android channel. Channels are used to collectively assign notifications to a single responsible channel. Users can manage settings for channels, e.g. disabling sound or vibration. Channels can be further organized into groups (see createChannelGroup).

By providing a groupId property, channels can be assigned to groups created with createChannelGroup.

The channel ID is returned once the operation has completed.

View the Channels & Groups documentation for more information.
