flutter_dtmf's Issues

No working on a Android Tablet

I ran my app on the following Android tablet : RugGEAR RG910, Android 8.0.0.
The code I used is the same I use and tested on several phones : Samsung A52, Pixel 6a, Pixel 4a, and a Xperia.
It works on all the phones.

On the tablet, I know the function is called, but no sound is played.
No error is displayed.
Of course I checked that the sound is on.

I also tried to run the exemple code, and it run with the exact same behaviour : no sound but no error on the tablet.
(I also run the exemple on my ohines for comparisons and it works)

I have no idea if the isuue is fom the tablet itself or its Android version.
Could anyone try to Run the exemple in another Android tablet and tell me if they have the same issue ?

ToneGenerator Crash if called a lot of time rapidely

I am using this library to play a sound very rapidely (up to every 200ms), and it randomly crash at some point.

Looking for this issue online, I have found a fix :
The Tone Grenerator must be released after each use with the following function : toneGenerator.release();

You can find the explaination here :
https://stackoverflow.com/questions/13463691/error-generating-beep-using-tonegenerator-class

I have tested the fix and it worked well for me so I will do a pull request for this fix.

"Error: Binding has not yet been initialized " when running on device "chrome"

When you try to run the example in a web browser flutter run -d chrome, the following exception is getting thrown:

❯ flutter run -d chrome                                                                                      [16:18:18]

Flutter Web Bootstrap: Programmatic
Error: Binding has not yet been initialized.
The "instance" getter on the ServicesBinding binding mixin is only available once that binding has been initialized.
Typically, this is done by calling "WidgetsFlutterBinding.ensureInitialized()" or "runApp()" (the latter calls the
former). Typically this call is done in the "void main()" method. The "ensureInitialized" method is idempotent; calling
it multiple times is not harmful. After calling that method, the "instance" getter will return the binding.
In a test, one can call "TestWidgetsFlutterBinding.ensureInitialized()" as the first line in the test's "main()" method
to initialize the binding.
If ServicesBinding is a custom binding mixin, there must also be a custom binding class, like WidgetsFlutterBinding, but
that mixes in the selected binding, and that is the class that must be constructed before using the "instance" getter.

Android compilation issues

The built failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetfier to solve the incompatibility.
✏️ Creating android/settings_aar.gradle...
[!] Flutter tried to create the file android/settings_aar.gradle, but failed.

Thank you.

Thanks for this. Using it here:

Can we set the Volume of the dtmf?

It would be great if it follows the platform settings

Error AUDIO_OUTPUT_FLAG_FAST denied by server

Since the last commit I have a new error, both on my Pixel 6A and a Sony Xperia.

The error is the following :

AUDIO_OUTPUT_FLAG_FAST denied by server;
E/AudioTrack(21895): AudioFlinger could not create track, status: -12
E/ToneGenerator(21895): AudioTrack(0x7e49992400) set failed with error -12

The weird thing is that the plugging do work without error on my Samsunf A52.

I digged the code a little bit and found a fix that seems to fix my error on both phone. I'll submit a pull request.
