2. Setup for IOS

Step 1: Open https://developers.facebook.com and create your application

Step 2: Once you have created the application, start adding the Facebook Login project.

Step 3: Select the IOS platform

Step 4: Start the IOS platform setup.

• In this step, we click next to skip

• we enter the Bundle ID of the IOS project.

• Open file project.pbxproj in your project flutter at ios/Runner.xcodeproj/project.pbxproj , search with keyword PRODUCT_BUNDLE_IDENTIFIER to get Bundle ID

• Return to the developer facebook page and enter bundle ID.
• Click the save button and then button Continue to continue

• Go back to the developer facebook, copy the code in the string tag under the key FacebookAppID

• Continue to open the info.plist file in your project flutter, find the keyword FacebookAppID and paste the code you just copied into the string tag as shown below.

• Complete setup for the IOS platform. Now setup project login.

Step 5: On the left menu, under **Facebook Login**, select Settings. Enter your Valid Oauth Redirect URLs url.

• Click Enable and enter App ID and App Secret in the previous step saved then click Save to finish.

• Oke completed the login and Facebook setup steps for IOS. Now run your app and check it out.

2. Setup for Android

Important note:

Because the project is separate between the develop and release, if you are not clear about the problem, you will be mistaken.

• When you build the debug, the application will retrieve keystore information at **android/key-debug.properties** . You can get the SHA1 code from the keystore file in folder **android/app**. In the case of using FluxStore's default keystore, the specific keystore path is
• android/app/mstore.keystore
• When you build release, the keystore information will be stored in folder **android/key.properties**. In the case of a build release, please call the build bundle script for the application to obtain the correct keystore.

Command build release android:

sh tools / build-appbundle.sh

In this case, the keystore file will be saved in folder certs/ of the project. If you build release, please get the SHA1 code of the keystore file at the path (default of FluxStore)

certs/key.jks

Step 1: Open the facebook developer page in the previous Setup for IOS step. On the left menu, select Quickstart -> select Android platform

Step 2: Start the Android platform setup.

• In this step, click next to continue

• In the import the Facebook SDK step we also ignore this by clicking next

Step 3: enter the package name of the android application in the project flutter and enter the Default Activity Class Name (it is package name with the MainActivity keyword at the end)

• Find the Package name by opening your project flutter and looking for file android/app/src/main/AndroidManifest.xml. In the second line of the file, we can easily get the package name.

• Enter the package name and Default Activity Class Name information, click Save and then Continue

• In this step, you need to add Release Key Hashes

• Copy the code Generating a Release Key Hash and return to your project flutter

• Open the file android/key-debug.properties (in case you are building debug) or file android/key.properties (In case you are building release) to get information about the keystore.
• Edit the code copied in the previous step keytool -exportcert -alias <name_alias> -keystore <path_of_file_keystore> | openssl sha1 -binary | openssl base64

// Build Debug
keytool -exportcert -alias mstoreapp -keystore android/app/mstoreapp.keystore | openssl sha1 -binary | openssl base64// Build Release
keytool -exportcert -alias key -keystore certs/key.jks| openssl sha1 -binary | openssl base64

(This script is demo on MacOS, on Android please try the similar script from the Facebook Guide)

• Once completed, copy the generated code and return to the Developer Facebook page

• Enter the code, press save and then continue

• Click Next to skip this step

• In this step, you copy the following 2 codes and paste them into the file android/app/src /main/res/values/strings.xml instead of the old code.

• Next steps click next to continue.

• Complete the setup process for android. Now build the app and test it.
