Suggestion: Flag unused imports after inlining platform checks

import { DateTimePickerAndroid } from "@react-native-community/datetimepicker";
import { Platform } from "react-native";

export default () => {
  if (Platform.OS === "android") {
    return DateTimePickerAndroid.open(datePickerOptions);
  } else if (Platform.OS === "ios") {
    // return something iOS specific
  } else {
    // return something else
  }
};

Metro can inline platform checks with a plugin. In the above example, targeting ios will make DateTimePickerAndroid unused. However, the import statement will remain and we will still import @react-native-community/datetimepicker on iOS. There should be a way to flag this as unused on certain platforms.

Start with the Metro inline platform-check plugin linked in the issue and inspect how platform-specific branches are transformed. Determine how unused imports should be detected after inlining, then verify that imports for excluded platforms are flagged or removed without affecting imports still used by the selected platform.
