Google announced some new Android features yesterday to make smartphones more convenient and safe - this includes the dark mode in Google Maps.
Google Maps gets the real dark mode

According to Android Police, the new dark mode is better than before as it removes all bright colour and replace them with muted pastels resulting in less screen fatigue. Google has been testing this since November last year and it's finally confirmed to be rolling out globally in Google's blog.
Other features on Android
There are a few other features that will be introduced such as voice-activated games and custom wallpapers on your display via Android Auto and using voice commands on Google Assistant even when you're across the room. You can even schedule your texts in Messages and use Password Checkup, a tool that will alert you if your password has been breached.
