+#### adaptiveIcon (for Android only)
+
+You can define adaptiveIcon for android:
+```yml
+flavors:
+  apple:
+    app:
+      name: "Apple App"
+  
+    android:
+      applicationId: "com.example.apple"
+      icon: "assets/icon/appleApp/ic_launcher.png"
+      adaptiveIcon:
+        foreground: "assets/adaptive_icon/appleApp/ic_launcher_foreground.png"
+        background: "assets/adaptive_icon/appleApp/ic_launcher_background.png"
+```
+After removing adaptiveIcon key, the adaptive icons generated before will still exist. Please delete adaptiveIcon manually.
