Can you show me a Code Sample on how you implement it? Also which Version of google_speech do you use?

Can you show me a Code Sample on how you implement it? Also which Version of google_speech do you use?

google_speech: ^4.3.0

The code looks ok so far. Could you please test whether your audio also contains data in release mode? It should be an array with different numbers.

[DiegoLimeiradaSilva]

I'm going to test, the question can't be the file extension?

[DiegoLimeiradaSilva]

That's right, the array is blank.. Strange that it works in debug.

[felixjunghans]

Ok, then there lies the problem. It looks like there is no audio file where you are looking or the file is empty or cannot be read. Since this is not a problem with google_speech, I would close the issue here.
