I have customized finish screen with banner image and have added multi-line label and 3 check boxes on that screen. In preview, everything seems fine. But after running the generated installer, banner is not there on the finish screen.
I tried using both default finish screen and empty form with banner.
Any idea what is causing this behavior?

I'm a developer who is developing a flutter.
I have a question about the default splash screen of the flutter.
I found that the first time I created the flutter project, it basically included a splash screen with a flutter icon.
I looked it up to erase the default splash screen, but I got a reply that it is not possible in the flutter/dart stage.
To solve this problem, first of all, I wanted to customize the defalut splash screen using the flutter_native_splash library.
However, the library did not meet my requirements because it was impossible to insert elements other than images (ex. text).
So, I used the flutter_native_splash library to insert an icon with only pure white color to create a fake splash screen.
And I made a real splash screen, registered it as the initial screen of the GetX library, and set it up to move on to the next page after the schedule delay.
You can check the ones described above in the video below.
In this situation, I have two questions.
First, I wonder if I can insert text into the splash screen using the flutter_native_splash library.
Secondly, I wonder if there is a way to delete the default splash screen that is automatically generated by the flutter.
The default splash screen cannot be overridden with Dart/Flutter alone. They are controls shown by the native Android/iOS context while the Flutter runtime is initializing. As such, any splash screen widget you create inside Flutter will show after the default splash screen. (Even if you completely remove the default splash image, the app would just be a blank while screen until Flutter finished loading, and that's bad design.)
There are instructions on how to change the default splash screen here :
For Android
Step 1: Go to android/app/src/main/res/drawable folder :
Here you will find a file launch_background.xml. This is where you can write some code and make it work.
Step 2: Open launch_background.xml
Step 3: Change Background
Uncomment line 7–11 and this is where you can change your background, maybe a color or image on line 4
<item android:drawable=”#color/ic_launcher_background” />
Step 4: Change Image/Icon
This is where (on line 10) you can change your app icon or to an image which will be in the center if android:gravity is center (Make sure you add your icons for different size devices for better result).
android:src=”#drawable/qart_trans”
And That’s it!! Woohoo
For iOS
Step 1: Open the project in iOS stuff in XCode
Step 2: Go to ios/Runner Folder
You will see here Assets.xcassets folder and LaunchScreen.storyboard. These are two things which we want.
Step 3: Open Assets.xcassets and click on LaunchImage
Paste your images/icons in 1x 2x 3x Options according to recommended sizes for devices
Step 4: Now Open LaunchScreen.storyboard
Click on the view and on the right panel click the down arrow like symbol change properties like background and content mode according to your need.
Step 5: Now Click the Image on the storyboard
Now on the right panel click the down arrow like symbol gain and change its properties as per need.
And That’s it again!! Voila!!!
According to this, a grey screen will appear when a Flutter app crashes due to a runtime error if the app is in release mode, and a red screen if in debug mode.
My app is showing a grey in MOST runtime errors, for example:
List<int> myList =[1,2,3];
int a = myList[5]
This will cause a
List index out of range.
Which is showing a grey screen in my device and the tester mentioned below.
But in one of my tester devices (Samsung s20) this black screen appeared.
Even if the app is deleted from cache and a newer version is installed, the app will open in this image with the same error.
My app isn't connected to any crash report services and the tester forgot how he had the error and in which page.
I'm now blind. Any suggestions on how to debug this? I've tried everything and the user also tried to get the error for a second time but we couldn't.
And why didn't this show a grey screen?
You probably didn't use Scaffold widget. You should wrap with Scaffold your used widget.
I am testing my app on HTC One M8 running Android version 5.0.2. When an input field in the app loses focus, a white background is shown after the keyboard closes.
My background image is set on .scroll-content, so I don't understand why it acts like this on Android.
Check your ionic pane colour and view colour. You have different background colour so in the keyboard adjust pane mode the view gets resized (height-keyboard height) so when the keyboard goes off it shows the ionic-pane colour. So override the '.pane' background colour and see will it make any difference.
keyboard adjustment will work only if '.scroll-content' is present. By default ionic-content will enable this
The issue is that when we open a keyboard in our current application the app gets resized to the area that is left after opening the keyboard and the Cordova webview is too slow in resizing the app back to its normal size after the user closes the keyboard. There is no proper solution to this problem.
The most elegant working workaround for is to stop resizing the application on keyboard open. The keyboard will just slide up and down on the form as an overlay and there will be no resizing required.
In AndroidManifest.xml file try to set windowSoftInputMode attribute to adjustNothing:
android:windowSoftInputMode="adjustPan"
This is not a solution and can be considered as an option for small forms but it is not suitable for big forms.
I realized an app for iOS. It all goes well, works like a charm... until the device is restarted! When I manually close the app (for example, on my iPad I slide four fingers upwards, visualize the menu showing the app "alive", hold the icon of the app and press the red badge, terminating the app) and I try to open it again this is what happens to me:
First the app remains stuck on the last page visited before closing the app (I cannot tap buttons on the tab bar or do anything else)
Then, the only thing I can do is tap the Home button and try to open the app again
At this point all I get is a perfectly black screen
The restart seems to be not a real restart, or not to be clean. This is totally meaningless to me. Am I missing something?
EDIT :
Remove your application by press Hold down Application iCon From simulator/device
And then re-install app. and check it worked or not ???
If your view display with black screen then give it backGround Color redColor or as u wish.
Its iOS app natural behavior only.
When you press Home button on device, While running any iOS app it goes in background but the The app is still in background and its save application's state.
So if you Tap agin app's icon you will get the last screen where did you leave it.
Now, if you want to Restart the app from initial you need to clear it.
Go this way.
Just double press device's Home button you can see running apps on bottom like this
For delete particular app, you simply press and hold, you can see red (-) icon on app
just click on that and you are on way.
Now press Home button and Go to Start app!!
The problem is that Xcode, when it runs an app, attach to it a debbuger which prevents it to close normally and causes problems in the reopening. Thank you very much to this guy who pointed out the problem: https://stackoverflow.com/a/15176137/1272105
I got fancybox working but I have this problem:
First, I can't make the loading image appear. And second, if I use a link to show an image on click, sometimes it fails to show it, because of the time it takes to load it (if it were an image instead of a link, it would have been already loaded by the browser, that's why it never fails with images).
In summary, I have a link, when I click it a modal window with an image should appear. Instead, a white box appears. If I reload the page, sometimes the image appears, sometimes it doesn't.
If it is working some of the time, maybe the problem is elsewhere? Is the picture you are loading particularly large, if you are shift refreshing I have experienced such effects in the past.
