ie: [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: FormatException: Invalid envelope about flutter_contacts HOT 9 CLOSED

I had the same problem. For solving this problem you should apply permissions on write data in contacts. It's a dangerous permissions, so add permission only in manifest is not enough. For call window applying or dinying permissions you can use permission_handler 4.2.0 .

await PermissionHandler().requestPermissions([PermissionGroup.contacts]);

After calling this method you can apply permission and contact will be added. By the way, this solution is needed only for android devices with Android 6.0 (API level 23) or higher. In lower versions you apply all permissions, when install your app.

Disclaimer: I am totally new to flutter. I can provide a full repo that compiles and runs, but this here is the offending code:

  void _saveNumber() {
    debugPrint('Saving number ${numberController.text}'); 
    PostalAddress address = PostalAddress(label: "Home");
    Contact contact = Contact(
      displayName: nameController.text,
      givenName: nameController.text,
      phones: [Item(label: 'mobile', value: numberController.text)],
      postalAddresses: [address]      
    );
    ContactsService.addContact(contact);
    setState(() {
      numberController.text = '';
      nameController.text = '';
    });
  }
