I am not aware of Android 12 having support for hiding the notification bar.

Do you mean that there is nothing we can do about this?

Yes

[Nathan617]

But can we change the color of the status bar during the splash?

Sometimes when the app launches, the status bar has the same color as the Splash Screen background colour, then it revert to black.

Same problem on my Android, many other apps can hide their notification bar during splash screen showing.

Or at least change the color of the notification/status bar this would be great

[jonbhanson]

@LastMonopoly are you talking about Android 12? Can you give me an example of an app that hides the notification bar on the native splash screen on Android 12?

@Nathan617 I don't think it is possible to change the color of the notification bar on the splash screen in Android 12. Just now I opened a couple dozen apps and they all had the same color for the notification area as the splash screen. It appears from your post that EMUI must handle the splash screen differently from Android.

My Huawei phone is using HarmonyOS 3.0, which is compatible with Android 12.

The left one is a normal android app, the right one is my app using flutter_native_splash with fullscreen: true

Same problem also happens on my Xiaomi, which is of Android 11.

[jonbhanson]

I don't have a device with HarmonyOS or Xiaomi, so I am not able to test any changes that would improve compatibility on these operating systems.

[LastMonopoly]

@jonbhanson Xiaomi is using Android 11, have you tested on Android 11?

[jonbhanson]

@LastMonopoly this package has been tested extensively with all recent versions of Android. Unfortunately, clones of Android like MIUI don't always work exactly the same as Android. Since I don't have any Xiaomi devices, there is no way for me to determine what needs to be changed to make the splash screen work the same as on Android. But like this example, if an Xiaomi user can tell me what needs to be changed and I can confirm it, I am happy to make changes to accommodate.

@jonbhanson I finally found a solution coming from this link :

https://stackoverflow.com/questions/72471785/how-to-change-status-bar-color-of-native-splash-screen-in-flutter

The solution is to go to project / android / app / src / main / res / values-night / styles.xml and to overwrite the <style name="LaunchTheme ... " section with the following code :

 <style name="LaunchTheme" parent="@android:style/Theme.Light.NoTitleBar">
        <!-- Show a splash screen on the activity. Automatically removed when
             the Flutter engine draws its first frame -->
        <item name="android:windowBackground">@drawable/launch_background</item>
        <item name="android:forceDarkAllowed">false</item>
        <item name="android:windowFullscreen">false</item>
        <item name="android:windowDrawsSystemBarBackgrounds">true</item>
        <item name="android:statusBarColor">@android:color/transparent</item>
        <item name="android:windowTranslucentNavigation">true</item>
        <item name="android:windowLightStatusBar">true</item>
    </style>

I now have the full screen during the splash as you can see below:

[LastMonopoly]

@Nathan617 Same result on my Huawei, the trick is
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
and /values-night/styles.xml

[LastMonopoly]

@Nathan617 @jonbhanson
This is my setup to achieve fullscreen, for styles.xml under values and values-night folder,
without <item name="android:windowTranslucentNavigation">true</item>

<style name="LaunchTheme" parent="@android:style/Theme.Light.NoTitleBar">
      <!-- Show a splash screen on the activity. Automatically removed when
           the Flutter engine draws its first frame -->
      <item name="android:windowBackground">@drawable/launch_background</item>
      <item name="android:windowDrawsSystemBarBackgrounds">true</item>
      <item name="android:statusBarColor">@android:color/transparent</item>
      <item name="android:windowLightStatusBar">false</item>
      <item name="android:forceDarkAllowed">false</item>
      <item name="android:windowFullscreen">true</item>
      <item name="android:navigationBarColor">#000000</item>
      <item name="android:windowLayoutInDisplayCutoutMode">shortEdges</item>
  </style>
