Add Map API Key

The app uses Google Maps for showing nearby locations of property. You need a Google Cloud API key with the Maps SDK for Android and Maps SDK for iOS enabled.

Step 1 — Open Google Cloud Console​

  1. Visit https://cloud.google.com/ and sign in with your Google account.
  2. Click Console (top-right) to open the Google Cloud Console.
  3. Create a new project, or select an existing one from the project picker.

Step 2 — Enable Required APIs​

In the left sidebar, go to APIs & Services → Library, then search for and enable the following APIs:

  • Maps SDK for Android
  • Maps SDK for iOS

For each one, click the API → Enable.

Step 3 — Create an API Key​

  1. Go to APIs & Services → Credentials.
  2. Click + Create Credentials → API key.
  3. Edit the newly created key. Add the APIs you enabled in Step 2. and tap Save
  4. Copy the generated API key — you will paste it into the app code in the next step.

tip

For production, restrict the key:

  • Application restrictions — Android apps (package + SHA-1) and iOS apps (bundle ID).
  • API restrictions — limit to Maps SDK for Android & iOS only.

Step 4 — Paste the Key into the App​

Android — AndroidManifest.xml​

Open android/app/src/main/AndroidManifest.xml and add the following <meta-data> tag inside the <application> tag:

<meta-data
    android:name="com.google.android.geo.API_KEY"
    android:value="YOUR_API_KEY_HERE"/>

Replace YOUR_API_KEY_HERE with the API key you copied in Step 3.

iOS — AppDelegate.swift​

Open ios/Runner/AppDelegate.swift and search for the following line:


    GMSServices.provideAPIKey("YOUR_API_KEY_HERE")

Replace YOUR_API_KEY_HERE with the same API key.

Step 5 — Rebuild​

flutter clean && flutter run

Maps should now load correctly on both platforms.

warning

Never commit your raw API key to a public repository. Use key restrictions (Step 3 tip) and consider storing the key in a non-tracked file for production builds.
