Question

how to let the splash page full screen in flutter? i got how to set splash page in flutter.dev

<resources>
<style name="LaunchTheme" parent="@android:style/Theme.NoTitleBar">
    <!-- Show a splash screen on the activity. Automatically removed when
         Flutter draws its first frame -->
    <item name="android:windowBackground">@drawable/launch_background</item>
</style>

Answer 1

Inside your Android module go to the app/src/main/res/values

Open up the file name styles.xml

Inside this file you will have a below code that is your custom style:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
        <!-- Show a splash screen on the activity. Automatically removed when
             Flutter draws its first frame -->
        <item name="android:windowBackground">@drawable/launch_background</item>
    </style>
</resources>

You need add the below line in it:

    <item name="android:windowFullscreen">true</item>

Like Below:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="LaunchTheme" parent="@android:style/Theme.Black.NoTitleBar">
        <!-- Show a splash screen on the activity. Automatically removed when
             Flutter draws its first frame -->
        <item name="android:windowBackground">@drawable/launch_background</item>
        <item name="android:windowFullscreen">true</item>
    </style>
</resources>

Once you add the above line app stays in fullscreen mode for the entire life-cycle. To disable it you need to define a normal theme to be applied to FlutterActivity after the launch screen is gone and in that theme add the above line with value "false".

Like Below:

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

    <style name="NormalTheme" parent="@android:style/Theme.Light.NoTitleBar">
        <item name="android:windowBackground">@drawable/launch_background</item>
        <item name="android:windowFullscreen">false</item>
    </style>

将您的图像放在 drawable 文件夹中并在 src 中调用它

<item><bitmap android:gravity="center" android:src="@drawable/splash" /> </item>
