问题描述

launch_background.xml

launch_background.xml

<?xml version="1.0" encoding="utf-8"?>
<!-- Modify this file to customize your launch splash screen -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/orange" />
    <!-- You can insert your own image assets here -->
    <item>
        <bitmap
            android:gravity="center"
            android:src="@drawable/splash_icon" />
    </item> -->
</layer-list>

styles.xml

<?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>
    <color name="orange">#FF9800</color>
</resources>

我可以动态更改应用程序中的原色值，并为应用程序设置主题颜色.我如何在这里发送原色-> <color name="orange">#FF9800</color>

I change the primary color value in the app dynamically and set theme colors for app. How can I send the primary color value here --> <color name="orange">#FF9800</color>

我还应该为IOS做什么?

Also what should I do for IOS?
