Open Contacts on device via icon tap flutter

问题

Is it possible to open the contacts on a device from an icon tap in flutter? I am able to open the phone function using url_launcher's plugin.I have used the contacts plugin but we dont have a need to manage contacts from our application, we want to use the phones functionality for managing contacts.

You can achieve this using Flutter platform channels and android Intent.ACTION_VIEW intent.

For example in your MainActivity register new channel and launch Contacts activity:

MethodChannel(flutterView, CHANNEL).setMethodCallHandler { call, result ->
            launchContactActivity()
        }

private fun launchContactActivity() {
        val intent = Intent(Intent.ACTION_VIEW)
        intent.type = ContactsContract.Contacts.CONTENT_TYPE
        startActivityForResult(intent, REQUEST_CODE)
    }

And on flutter side:

void launchContacts() async {
    try {
      await platform.invokeMethod('launch');
    } on PlatformException catch (e) {
      print("Failed to launch contacts: ${e.message}");
    }
    setState(() {
    });
  }

Please see full example. Hope this help.

Probably you can't directly.

But you can fetch them and their info with contacts_service package.

Hope this could help you.
