https://flutter.dev/docs/development/ui/splash-screen/android-splash-screen
On this page, there are three types of splash themes mentioned
A. Launch theme
B. Normal theme
C. Flutter splash theme
Now i have read through it and tried implementing all of these, but can someone experienced enough tell me where all these three screens appear during the app launch?
P. S. :- There is a fourth type of splash screen that youtubers tutorial about, that splash screen appears as a first widget drawn by flutter so it's not really a splash screen. It's a first widget to be drawn.
Any help would be appreciated.
Splash screens are typically used by particularly large applications to notify the user that the program is in the process of loading. Nowadays, in mobile apps splash screen is common. Flutter docs mention a native way to implement a splash screen. This splash screen is white by default. You can see a white screen on the launch of the app.
https://flutter.dev/docs/development/ui/splash-screen/android-splash-screen
This document mentions steps to edit this white screen.
A - Launch Theme
The launch theme is displayed when the app is initializing. This is the very first thing seen on launching the app, even before our homepage is loaded.
B - Normal ThemeProvide the default theme for C-Flutter Splash Screen
C - Flutter Splash Screen
Each Flutter experience in an app requires a few moments to initialize the Dart isolate that runs the code. This means a user momentarily sees a blank screen until Flutter renders its first frame. This can be seen for a very brief moment after the splash screen disappears and also in some other situations mentioned in docs.
D- First widget as Splash Screen
I think this is not the proper way to implement a splash screen as per Flutter docs. But by displaying a widget as a splash screen it offers all the flexibility of flutter to design a custom splash screen, especially for beginners.
If you need to see the changes, follow the docs with implementing each splash screen with different colors or designs, so that you can identify the changes quickly.

I have a request to reduce my app screen size and the rest of the screen space are still visible and clickable for user.
It means when my app is running, user can click some icons or buttons outside of my application.
What I found are using such as Dialogs or Multiple Fragments. However, those solutions are useful when all are in your main activity. But in my case, the rest of the screen is from Home screen or other screens, not from my app screen.
Could someone have an idea for this kind of concept?
Here is my request concept image

You don't need to do anything for this. Android supports splitt screen since Android 7.0.
Alternatively you can enable Picture-In-Picture mode for your app which is supported since Android 8.
Our Android app may present sensitive data and we wish to hide it when the app is not in use - Android is taking a snapshot of the app and displays it in the overview screen. At the same time we want to enable the user to take screen shots of the app when using it. We already checked following options:
Using FLAG_SECURE - Answers the need to hide the app in the overview screen but completely blocks the user from taking any screen shot of the app
Using onPause to change the activity content. Specifically we tried to show there the splash screen. We do see the splash screen appears when the app is minimizing, but the thumbnail presents the app before the splash appeared, meaning this is too late.
Any idea how we can hide/change the activity before the app moves to the background and still keep the print screen ability when the user is using the app?
Here are some links about the issue - all are only partial to this question:
How do I prevent Android taking a screenshot when my app goes to the background?
Hide a view before onStop?
Thanks!
Is removing the app from recent apps completely an option? Then set android:excludeFromRecent to true for the activity.
I need a screen control (possibly but not mandatory an app widget) that will seat
on Android's homescreen and will always be visible to the user - even when he scrolls the homescreen to the next page.
Please help me if any body have done this before.
I think the only way you will be able to do this is if you implement your own Launcher.
The functionality that you're looking for, being able to place a static widget on every screen of the launcher regardless of how many screens they have, isn't currently available in Android, nor any of the launcher apps out there (Go launcher, ADW, Launcher pro etc) nor any of the versions of Android which have been rewritten by the phone manufacturers (HTC's Sense, Samsungs Touch Wiz etc)
It's a big job to write a Launcher yourself, but the stock Android Launcher code is available to play about with from https://android.googlesource.com.
I am developing an android widget to show in the homescreen. Now, I can show the widget in main homescreen. Now, is there any way to show that widget every homescreens (in most of the devices there are several homescreens where we can swipe to left or right from the homescreen)?
Only if the user manually adds your app widget multiple times.
These depends on entirely on the home screen app. Some home screen apps could certainly implement a UI to have a widget like this. The launcher that is part of stock Android does not have such a facility.
When my application is killed due to being in the background for too long (Android freeing resources) or user using task killer or something similar, in onCreate I detect new application state and execute some initializations that my app needs to work properly. While this initialization is taking place, screen turn white and my app name is written in the top left corner (this is, I guess, what Android does by default). After 1-3 seconds, after all my app settings are recreated, my app screen shows up.
I am using my own header which is understandingly not shown during this "white phase".
My question is how can I customize this white screen? or at least I would be happy if I can remove my app name since it looks weird (positioned to left, no margins, etc..) and have only white screen.
I noticed that Gmail app has white screen only when similar happen.
Any ideas are welcomed.
Thanks,
