11 months ago Hey @aanchalMicro, I'd be happy to help you with adding the functionality for seeking forward and backward in a sound wave recorder! Below is an explanation of how you can implement these features in your Flutter app.
First, let's address the forward functionality: Seek Forward Functionality: void forwardAudioByDuration(Duration duration) { if (_isPlayingAudio) { final currentPosition = playerController.currentPosition; final targetPosition = currentPosition + duration; final maxDuration = playerController.duration;
if (targetPosition < maxDuration) { playerController.seekTo(targetPosition); } else { playerController.seekTo(maxDuration); } } }
In this code, forwardAudioByDuration takes a Duration as an argument and calculates the target position for seeking forward. It then checks if the target position is within the bounds of the audio duration and seeks to that position using playerController.seekTo.
Forward Button to Seek: GestureDetector( onTap: () { forwardAudioByDuration(Duration(seconds: 5)); // Seek forward by 5 seconds }, child: Image.asset( "assets/images/forward.png", height: SizeConfig.screenHeight * 0.08, ), ),
Seek Backward Functionality: void backwardAudioByDuration(Duration duration) { if (_isPlayingAudio) { final currentPosition = playerController.currentPosition; final targetPosition = currentPosition - duration;
if (targetPosition > Duration.zero) { playerController.seekTo(targetPosition); } else { playerController.seekTo(Duration.zero); } } } Similar to the forward functionality, backwardAudioByDuration calculates the target position for seeking backward and ensures it's within bounds before seeking using playerController.seekTo.
Backward Button to Seek: GestureDetector( onTap: () { backwardAudioByDuration(Duration(seconds: 5)); // Seek backward by 5 seconds }, child: Image.asset( "assets/images/backward.png", height: SizeConfig.screenHeight * 0.08, ), ),
Make sure you adjust the Duration values and UI components according to your design and requirements. With these implementations, your users should be able to seek forward and backward within the audio playback.
Remember to handle state changes appropriately, especially if you are using a state management solution like Provider.
Working in flutter need solution for recording sound with wave form and forward it by 15 seconds , I tried many solutions but they were not helpful like using duration custom or custom..... also used this package audio_waveforms but didnt worked if anyone could help please respond asap
