[20] - Created an Example Form that can be filled with voice commands using digit components

[EuclidStellar]

Description

#20
This PR adds a voice-command feature to fill a form in the app. The form consists of three fields: Name, Phone Number, and Email. Users can fill these fields by speaking into the microphone. The app uses the speech_to_text package to convert speech to text and the flutter_tts package to convert text to speech. Additionally, the app utilizes the DigitTextField widget from the digit_components package to create the form fields.

Features Added:

1. Voice Command to Fill Form Fields:

   • The app listens for voice commands when a field is focused and updates the corresponding field with the recognized text.
   • The app speaks the label of the focused field to guide the user on what to say.

2. Form Validation:

   • The app uses the Form widget to validate the form fields.
   • A snackbar is displayed when the form is successfully submitted.

3. User Interaction:

   • The app uses the IconButton widget to start and stop listening for voice commands.
   • The FocusNode widget is used to track which field is currently focused.
   • The ScaffoldMessenger widget is used to show a snackbar when the form is successfully submitted.
   • The FlutterTts widget is used to speak the label of the focused field.

Packages Used:

• Fluttertts
• Speech to text
• Digit components
