Enhancement #160 #161 (Make phone numbers and email addresses interactive)

[Ninad07]

What I did
Made phone number and email address field interactive by opening the respective phone/messagin/mail app the user selects, after tapping on the phone number and email address field.

How I did it
I used a flutter package url_launcher for the purpose. In the already provided GestureDetector widget for the phone number field (custom_card.dart), in the onTap function, I used the prebuilt methods from the package to open the phone and messaging or email app with the phone number/email precomposed as soon as the user selects the app

How to verify it
For verification, just tap on the phone number of the user, whose profile page you are on, currently. It opens an intent bottom sheet asking us to select the respective phone number or messaging app we want to use (get redirected to). Select any. It will open the selected app and we can see the recipient's field already composed with the same phone number.

Description for the changelog
Made the phone number and email address field interactive by providing phone number, messaging and email app options for the users to select and get redirected to the selected app.

@Ninad07 This is not working on iOS simulator.

Alright. I'll recheck

@nitesh2599 Regarding IOS, I checked through Flutter Inspector and it seemed to work. Moreover, the package url_launcher supports both the platforms. I have still made another commit combining issue #160 and #161. Can you please check again once?
