 To verify a user's email, first send a verification email with a redirect URL. The verification secrets will be appended as query parameters to the redirect URL:

 After the user clicks the link in the email, they will be redirected to your site with the query parameters `userId` and `secret`. If you're on a mobile platform, you will need to create the appropriate deep link to handle the verification.
 
 Next, implement the verification page that handles the redirect:
 
+{% multicode %}
 ```client-web
 import { Client, Account } from "appwrite";
 
 const client = new Client()
-    .setProject('<PROJECT_ID>'); // Your project ID

 # Phone verification {% #phone-verification %}
 
 To verify a phone number, first ensure the user has a phone number set on their account:
 
+{% multicode %}
 ```client-web
 const response = await account.updatePhone(
     '+12065550100',  // phone
     'password' // password
 );
 ```
 
+```client-flutter
+Future result = account.updatePhone(
+    phone: '+12065550100',
+    password: 'password'
+);
+
+result.then((response) {
+    print(response);
+}).catchError((error) {
+    print(error.response);
+});
+```
+
+```client-apple
+let response = try await account.updatePhone(
+    phone: "+12065550100",
+    password: "password"
+)
+```
+
+```client-android-kotlin
+val response = account.updatePhone(
+    phone = "+12065550100",
+    password = "password"
+)
+```
+{% /multicode %}
+
 Then initiate verification by calling `createPhoneVerification`:
 
+{% multicode %}
 ```client-web
 const response = await account.createPhoneVerification();
 ```
 
+```client-flutter
+Future result = account.createPhoneVerification();
+
+result.then((response) {
+    print(response);
+}).catchError((error) {
+    print(error.response);

+
+```client-apple
+let response = try await account.createPhoneVerification()
+```
+
+```client-android-kotlin
+val response = account.createPhoneVerification()
+```
+{% /multicode %}
+
 After the user receives the verification code, complete verification by calling `updatePhoneVerification`:
 
+{% multicode %}
 ```client-web
 const response = await account.updatePhoneVerification(
     '[USER_ID]',  // userId
     '[SECRET]' // secret
 );
 ```
 
+```client-flutter
+Future result = account.updatePhoneVerification(
+    userId: '[USER_ID]',
+    secret: '[SECRET]'
+);
+
+result.then((response) {
+    print(response);
+}).catchError((error) {
+    print(error.response);
+});
+```
+
+```client-apple
+let response = try await account.updatePhoneVerification(
+    userId: "[USER_ID]",
+    secret: "[SECRET]"
+)
+```
+
+```client-android-kotlin

+    userId = "[USER_ID]",
+    secret = "[SECRET]"

 # Role-based access {% #role-based-access %}
 
 You can restrict resource access to verified users only using permissions through the `user([USER_ID], "verified")` role. This role is automatically assigned after successful verification.
