How to get the original image in the splash

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#android:color/white" />
<!-- You can insert your own image assets here -->
<item>
<bitmap
android:gravity="center"

<?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="?android:colorBackground" />
<!-- You can insert your own image assets here -->
<item>
<bitmap

android:src="#drawable/bluetoothicon"
android:width="100dp"
android:height="100dp" />

<item android:drawable="?android:colorBackground" />

Output
I am having trouble removing the white screen that appears before my splash screen. I saw many videos and followed their instructions but still, that white screen don't go away. I am a beginner so I don't have much knowledge to solve it, kindly help!
I am using initState to show the splash screen. I have also put my splash image inside the drawable folder and this is how my launch_background.xml file looks like:
<?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="#android:color/black" />
<!-- You can insert your own image assets here -->
<item>
<bitmap
android:gravity="center"
android:src="#drawable/splash" />
</item>
</layer-list>
Okay, so my problem was solved when I added my splash in styles.xml file:
<item name="android:windowBackground">#drawable/splash</item>
I have set an image in launch_background.xml file for splash screen. it takes around 5sec to switch to next page. how to reduce display time.
<?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="#android:color/white" />-->
<!-- You can insert your own image assets here -->
<item>
<bitmap
android:gravity="center"
android:src="#mipmap/splash_screen" />
</item>
</layer-list>
Please suggest how to reduce display time?
I think you are running app in debug mode so it will take time. I will suggest you run the app in release mode. by running this command in terminal.
flutter run --release
By default, flutter run compiles to debug mode. Your IDE supports this mode. Android Studio, for example, provides a Run > Debug… menu option, as well as a green bug icon overlayed with a small triangle on the project page.

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>
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>
Put your image inside the drawable folder and call it in src
<item><bitmap android:gravity="center" android:src="#drawable/splash" /> </item>
I want to following features in buttons in android button:
Buttons should change colours when clicked
Some specific buttons have features like the background color of button should remain changed until we press another button.
For rounded corners you can use below code :
#drawable/rounderd_corner.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#android:color/transparent" />
<stroke
android:width="1dp"
android:color="#color/YOUR_COLOR" />
<corners
android:bottomLeftRadius="8dp"
android:bottomRightRadius="8dp"
android:topLeftRadius="8dp"
android:topRightRadius="8dp" />
And For selector Buttons use below #drawable/select_button_color.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/YOUR_COLOR" />
<corners
android:bottomLeftRadius="8dp"
android:bottomRightRadius="8dp"
android:topLeftRadius="8dp"
android:topRightRadius="8dp" />
And Change background resource when button is clicked
For circular and for changing color when selected/not-selected button you can use following code snippet
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="false">
<shape android:shape="oval">
<solid android:color="#color/colorPrimary"/>
</shape>
</item>
<item android:state_pressed="true">
<shape android:shape="oval">
<solid android:color="#color/colorPrimaryDark"/>
</shape>
</item>
</selector>
And you problem will be solved, hope it helps.
