Have you tried on Pixel 4? Check this thread https://stackoverflow.com/questions/5916521/how-can-you-make-the-android-emulator-support-speech-recognition

I believe it has something to do with the emulator needing the google search feature ( i could be wrong)

Yes, that's right, you must make sure that the emulator has support. I think the README has some links on how to set that up.

1. I think this exception occurs on emulators don't support google play. I wonder Speech_To_Text package can return an error, is it better than throw an exception? because I think many developers want to test other functions on these emulators.

2. "checks if a speech recognizer is available on the device before completing initialize"
   I'm a newbie in flutter, I don't find how a way to check a speech recognizer is available on the device in programming, could you help me?

3. Another question: I don't find anywhere define about all error message that the package can return. I need it to handle and show message to user, may I have?

[sowens-csd]

1. You can catch the exception with a try, but yes, I probably will change this to a false response and an error at some point.
2. I misremembered, I'd thought there was a separate test to see if speech recognition is available but I see that it is embedded as part of the initialize call. In fact it's that test that you're hitting to get the exception you're seeing.
3. The documentation for the SpeechErrorListener type has the current list of errors. I see that it has gotten slightly out of date so I'll update in an upcoming release.

Thank you so much, I got it.
