How to create a custom audio player for your FlutterFlow app?

In this tutorial, we will walk through how to create a custom audio player for your FlutterFlow app. FlutterFlow is a powerful and intuitive platform that simplifies the application development process. Despite its simplicity, it also provides both the basic and advanced functionalities needed to create complex and feature-rich apps.

Before You Begin

To follow and implement these steps, you need to have Flutter and Dart SDK installed on your machine and an existing FlutterFlow application that you'd like to add the audio player to.

Step 1: Create a New Screen

For the purpose of our audio player, let's create a new application screen.

Go to the Screens section in your FlutterFlow project. Click on the '+ Add Screen' button. Name the new screen as ‘AudioPlayer’.

Step 2: Design the Audio Player Screen

Select the new screen and create a custom design for the audio player. Add necessary elements to the screen that is required by a audio player such as play, pause and stop buttons. Use the easy drag-and-drop feature of FluterFlow for this purpose.

Step 3: Install the Audio Player Package

The next step is to add the necessary package for handling audio playback. Go to the Pubspec.yaml file of your project and add the following line under dependencies:

audioplayers: ^0.19.4

Note: Always check Pub.dev and use the latest version of necessary packages.

Step 4: Import the Audio Player Package

Go to the code part of your FlutterFlow project and import the audio player package by adding this import statement at the top of your Dart file:

import 'package:audioplayers/audioplayers.dart';

Step 5: Declare an Audio Player Instance

Next step is to declare the audioplayer instance. Add these lines of code to create a new instance of AudioPlayer:

AudioPlayer audioPlayer = AudioPlayer();

Step 6: Create Functions for Play, Pause and Stop

Create functions for playing, pausing, and stopping the audio. For this, write the implementations inside the backend of the three buttons we have previously created.

Here is how you can implement these:

void playAudio() async {
  int result = await audioPlayer.play('url_to_your_audio_file');
}

void pauseAudio() async {
  int result = await audioPlayer.pause();
}

void stopAudio() async {
  int result = await audioPlayer.stop();
}

Replace 'url_to_your_audio_file' with the actual URL of your audio file.

Step 7: Connect the Functions to Buttons

Next, return to the FlutterFlow UI and connect these functions to the corresponding buttons through the 'Actions' settings in the Styles tab.

It’s important to note that in FlutterFlow, user actions on elements of your app trigger events and you can specify the actions to be taken when these events are triggered.

Step 8: Test the Audio Player

The final step will be to test your audio player. Simply run the project and check if the audio player works as expected.

This is a basic implementation of an audio player. Depending on your app requirements, you might want to add more complex functionalities like sliders for tracking the progress of the audio being played, controls for volume, looping the audio, and so on. But this guide gives you a starting point from which to build a more feature-rich audio player for your FlutterFlow application.
