DefaultProcessTextService class

The service used by default for the text processing feature.

Any widget may use this service to get a list of text processing actions and send requests to activate these text actions.

This is currently only supported on Android and it requires adding the following '' element to the Android manifest file:

<manifest ...> <application ...> ... <!-- Required to query activities that can process text, see: https://developer.android.com/training/package-visibility and https://developer.android.com/reference/android/content/Intent#ACTION_PROCESS_TEXT.

     In particular, this is used by the Flutter engine in io.flutter.plugin.text.ProcessTextPlugin. -->
<queries>
    <intent>
        <action android:name="android.intent.action.PROCESS_TEXT"/>
        <data android:mimeType="text/plain"/>
    </intent>
</queries>

The '' element is part of the Android manifest file generated when running the 'flutter create' command.

If the '' element is not found, queryTextActions() will return an empty list of ProcessTextAction.
