Here's my code below. I have added soundName value to sound file name. I have added sound file to 'raw' folder in android directory. But still it is playing default notification sound.
PushNotification.localNotification({
/* Android Only Properties */
channelId: 'default-channel-id',
autoCancel: true,
largeIcon: 'ic_launcher',
smallIcon: 'ic_launcher',
color: 'red',
vibrate: true,
vibration: 300,
tag: 'some_tag',
group: 'group',
groupSummary: false,
ongoing: false,
actions: null,
invokeApp: true,
when: null,
usesChronometer: false,
timeoutAfter: null,
/* iOS only properties */
category: '',
/* iOS and Android properties */
id: this.lastId,
title: config.title,
message: config.message,
userInfo: {screen: 'home'},
playSound: true,
soundName: 'sound_one.mp3',
number: 10,
});
