Get API errors from Laravel into Flutter - php

Question

I'm using this code for User Sign Up in Laravel:
class UsersController extends Controller
{
public function register(Request $request)
{
$validatedData = $request->validate([
'name' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'password' => 'required|string|min:8',
'phone' => 'required|unique:users',
'type' => 'boolean',
'verified' => 'boolean'
]);
$user = User::create([
'name' => $validatedData['name'],
'email' => $validatedData['email'],
'phone' => $validatedData['phone'],
'type' => $validatedData['type'],
'verified' => $validatedData['verified'],
'password' => Hash::make($validatedData['password']),
]);
$token = $user->createToken('auth_token')->accessToken;
return response()->json([
'user' => $user,
'access_token' => $token,
'token_type' => 'Bearer',
]);
}
As you can see , some of my field are unique , so I want to display a message in my front side that displays the error from the back side.
Exemple : When a user enters a used phone number , I want to return an error saying : this phone number has been used .
How can I achieve this ? Thank you.

You can get a User record from the database by phone. If the record exists, then do your logic
class UsersController extends Controller
{
public function register(Request $request)
{
$validatedData = $request->validate([
'name' => 'required|string|max:255',
'email' => 'required|string|email|max:255|unique:users',
'password' => 'required|string|min:8',
'phone' => 'required|unique:users',
'type' => 'boolean',
'verified' => 'boolean'
]);
// get a user record by phone
$record = User::where('phone', $validatedData['phone'])->find();
if (!empty($record)) {
return response()->json([
'error' => 'this phone number has been used'
])
}
//.....
}
