Platform is Android
Running "flutter packages get" in project_activity...
The current Dart SDK version is 2.3.0-dev.0.5.flutter-a1668566e5.
Because project_activity depends on flutter_tts >=0.0.2 <0.0.7 which requires SDK version >=1.8.0 <=2.0.0, version solving failed.

Is there any way to make it work? I have tried nearly all the code available for flutter_tts. It is still not working for me. It will be a huge favor if you can guide me a little.

Great plugin! Any chance you can add support for onRangeStart (Android) and willSpeakRangeOfSpeechString (IOS)??
I'm porting my Swift/IOS app to Flutter/Android, it uses this callback to highlight each utterance as it is spoken, giving useful feedback to the user that the app is actually speaking (if the volume is off, for example).
I'd do a pull request but I'm running flat out to hit a hard deadline at the moment ;) but FWIW I implemented a quick version in a local copy (Android only) with the following:
// In FlutterTtsPlugin.java within utteranceProgressListener..
// ...
@OverRide
public void onRangeStart(String utteranceId, int start, int end, int frame) {
ArrayList offsets = new ArrayList<>(3);
offsets.add(Integer.valueOf(start));
offsets.add(Integer.valueOf(end));
offsets.add(Integer.valueOf(frame));
channel.invokeMethod("speak.onRangeStart", offsets);
}
// ...
// In flutter_tts.dart..
typedef void RangeHandler(dynamic offset);
// Within FlutterTts
RangeHandler onRangeStartHandler;
void setRangeHandler(RangeHandler callback) {
onRangeStartHandler = callback;
}
// New case
Future platformCallHandler(MethodCall call) async {
switch (call.method)
// ...
case "speak.onRangeStart":
if (onRangeStartHandler != null) {
onRangeStartHandler(call.arguments);
}
break;
// ...
I followed the Example properly, and it works perfectly on android, but it just doesn't work on IOS. Please help. Thanks a ton.
It doesn't work on the IOS speaker nor the Headphones.
On Android, the setLanguage function ignores the country code:
flutterTts.setLanguage("en-GB") // doesnβt work, "en-US" is choosen
The problematic java line:
void setLanguage(String language, Result result) {
Locale locale = new Locale(language); // You should split the language: new Locale("en", "GB");

package. However, after upgrading, it behaves weirdly. It speaks the first thing I throw at it, but I am receiving the error below, and after that it won't speak anything anymore.

I believe this worked before but seems not after upgrading to flutter_tts: 0.2.0. Tested Android only.
flutter run --release
Version: 0.2.0
Platform:
Flutter's new background execution feature (described here: https://medium.com/flutter-io/executing-dart-in-the-background-with-flutter-plugins-and-geofencing-2b3e40a1a124) allows plugins to be registered in a background context (e.g. a Service). The problem is that flutter_tts assumes that the context for plugin registration is an activity with this line of code:
channel.setMethodCallHandler(new FlutterTtsPlugin(registrar.activity(), channel));
registrar.activity()
may now return null, and this leads to a NPE:
E/AndroidRuntime(12425): Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.content.Context android.app.Activity.getApplicationContext()' on a null object reference
E/AndroidRuntime(12425): at com.eyedeadevelopers.fluttertts.FlutterTtsPlugin.<init>(FlutterTtsPlugin.java:32)
E/AndroidRuntime(12425): at com.eyedeadevelopers.fluttertts.FlutterTtsPlugin.registerWith(FlutterTtsPlugin.java:82)
E/AndroidRuntime(12425): at io.flutter.plugins.GeneratedPluginRegistrant.registerWith(GeneratedPluginRegistrant.java:23)
The solution is to change the above line of code to this:
channel.setMethodCallHandler(new FlutterTtsPlugin(registrar.activeContext() , channel));
(and change the declared type of the constructor's first parameter accordingly from Activity to the more general Context).
I am unaware of whether there is a similar bug on the iOS side.
No NPE.
There are 3 sample projects from Google that I am aware of that demonstrate background execution:
https://github.com/bkonyi/FlutterGeofencing
https://github.com/flutter/plugins/tree/master/packages/android_alarm_manager
https://github.com/flutter/plugins/tree/master/packages/location_background
The first is for Android/iOS. The second is Android only. The third is iOS only.
To reproduce the problem, just add the flutter_tts plugin as a dependency to one of the first two projects and run the app (you may need to use the appropriate feature of the app that triggers background execution).

When adding flutter_tts and flutter_twitter_login to an objective-c enabled flutter project we get compiler issues.
Adding flutter_tts on its own works without issue & there is no need to create a swift enabled project.
Just need to ensure :
Follow the steps above to add flutter_tts to your Obj-c flutter project. Now add flutter_twitter_login (https://pub.dev/packages/flutter_twitter_login) and ensure in your podfile you set podfile:ios, '11'
do a pod deintegrate and then flutter clean, followed by flutter pub get and finally a pod install.
Ensure one of your files (say main) imports from flutter_twitter_login.
This will install the flutter_twitter_login.
When you try and run, you will get lots of compiler issues - a snapshot is shown here - the issue appears to be one of linking whereby the header files are not found.

I added this in the build.gradle

And I got this result:

^
1 warning
Looking at the API reference for getDefaultLanguage()
it says that it's deprecated since API level 21.
However in build.gradle
we do specify:
minSdkVersion 21
That's why I think that the following ternary should be replaced:
Locale locale = Build.VERSION.SDK_INT >= Build.VERSION_CODES.M
? tts.getDefaultVoice().getLocale()
: tts.getDefaultLanguage();
This gets the job done without any warning and is valid since our minSdkVersion
is 21:
Locale locale = tts.getDefaultVoice().getLocale();
No warning.

Hi, is it possible to do voice selection on iOS? I've seen #16 which implement for Android, not sure whether native iOS allow similar behavior. Thanks!
Sometimes the completion handler doesn't call and it doesn't talk. Others is does, but I noticed when I switch to a new a page in my app that also has an instance of the plugin, sometimes when I return to the original page the completionhandler doesn't fire and it doesn't talk. I've narrowed it down to being this, but I'm not sure why.
I'm on the latest version of the plugin.
I am having an issue with the IOS integration for this plugin.
Background:
I know there is an known issue using the Objective-C template but I am trying to add this plugin to my app that has a lot of custom iOS already in it (specifically a ShareExtension) and it would be a pain to recreate the app using the Swift template.
Somewhat solution:
I followed the advice seen here: https://github.com/flutter/flutter/issues/16049#issuecomment-382664356 and was able to get rid of the Swift version fault but now I am encountering another fault (shown below) and have been unable to fix it. My Swift programming is very minimal so I would appreciate any help you can give. Thanks!

Because flutter_tts 0.0.6 requires SDK version >=1.8.0 <=2.0.0 and no versions of flutter_tts match >0.0.6 <0.1.0, flutter_tts ^0.0.6 is forbidden.
So, because kbml_viewer depends on flutter_tts ^0.0.6, version solving failed.
pub get failed (1)
text is played too fast,
Configuration:
_flutterTts = new FlutterTts();
await _flutterTts.setLanguage("es-ES");
await _flutterTts.setSpeechRate(1.0);
await _flutterTts.setVolume(1.0);
await _flutterTts.setPitch(0.5);
await _flutterTts.isLanguageAvailable("es-ES");

I need to play a silence before starting to speak.
When using Bluetooth headsets with batteries the Headsets normally switches off the audio when there is no signal from the device for a while in order to save battery. When flutter_tts starts to speak some headsets needs 500-1500ms to restart and play the audio file. Without a trailing signal the user will not hear the first second of the audio.
When playing the silence the Headset will detect the (silent) signal and starts up.
So I ask to add a feature to define a silence period in milliseconds before starting the speech.
Optional: For advanced functionality another parameter could be added to define that the silence period will be omitted if the last speech is not older than x seconds. (assuming that the headset is still active)
In android I had the following code snippet:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
if (silenceMs > 0)
tts.playSilentUtterance(silenceMs, TextToSpeech.QUEUE_ADD, utteranceId);
tts.speak(speak, TextToSpeech.QUEUE_ADD, null, utteranceId);
} else {
if (silenceMs > 0)
tts.playSilence(silenceMs, TextToSpeech.QUEUE_ADD, null);
tts.speak(speak, TextToSpeech.QUEUE_ADD, null);
}
I already have a project and there is no dependency on Swift anywhere.
When I try to add flutter_tts there start to appear build errors.

Whether to support mixed Speech of two languages
For example: English and Chinese are in a paragraph. If I set the English mode, the voice cannot read another language correctly.
Text case: 'testοΌζ΅θ―'(ζ΅θ― is Chinese after translation)
The does not change.
One should here a difference with respect to the sound volume, after setting this statement in the initTts() method:
flutterTts.setVolume(1.0);
or
flutterTts.setVolume(10.0); //the sound should be louder
see the statements above.
Latest version of flutter_tts

Running "flutter packages get" in music_player...
The current Dart SDK version is 2.1.0-dev.5.0.flutter-a2eb050044.
Because sample_app depends on tts any which requires SDK version >=1.8.0 <=2.0.0, version solving failed.

I am receiving the following error : W/TextToSpeech( 8234): speak failed: not bound to TTS engine.
Do you know how to resolve it?
Having multiple instances of a StatefulWidget that instantiates FlutterTts (in the same tree) presents a problem. The state of the last instance overrides the state of any previous instance in the tree. It seems as though this plugin doesn't support multiple instances...
Provide question related to this flutter plugin.
I encountered this problem, but the android version 5.0.1 cannot be changed, how should I modify the code to solve this problem
Android Voice Selection.
tts.setvoice() implementation (so we can select male or female voices) can be done by setting de voice number in default voice in setup, but it would be nice to be able to do this from the app.
Hi Friend
I my app i use two language en-us, en-gb
When i call func speak() and use
await flutterTts.setLanguage(language);

Whenever I try to build my project, the build seems to complete and then throws this error and I'm stuck. I have searched all through the internet still haven't seen anything that works.

I must add this is only specific to IOS.
Everything works fine in android.
I get this error when I try run on a real device:
Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 21 declared in library [:flutter_tts] C:\my-dev\Projects\flutter\mijn_italiaans\build\flutter_tts\intermediates\manifests\full\debug\AndroidManifest.xml as the library might be using APIs not available in 16
Suggestion: use a compatible library with a minSdk of at most 16,
or increase this project's minSdk version to at least 21,
or use tools:overrideLibrary="com.eyedeadevelopers.fluttertts" to force usage (may lead to runtime failures)

I tried adding

I also made sure that hi-IN
language is available
but each time I was getting an error via error handler as
