+## **bundle_deps_filter**: [label list] A list of labels that are filtered out.
+
+```
+  A list of target labels.
+
+  This list contains target label patterns that should be filtered out
+  when creating the bundle. Any target matching one of those label will
+  be removed from the dependencies of the create_bundle target.
+
+  This is mostly useful when creating application extension bundle as
+  the application extension has access to runtime resources from the
+  application bundle and thus do not require a second copy.
+
+  See "gn help create_bundle" for more information.
+
+```
+
+### **Example**
+
+```
+  create_bundle("today_extension") {
+    deps = [
+      "//base"
+    ]
+    bundle_root_dir = "$root_out_dir/today_extension.appex"
+    bundle_deps_filter = [
+      # The extension uses //base but does not use any function calling
+      # into third_party/icu and thus does not need the icudtl.dat file.
+      "//third_party/icu:icudata",
+    ]
+  }
+
+
+```
