How to use an image asset with .ai extension in Flutter?

For example, image.ai is the file name. I am unable to use it regularly. Is there something specific I must to do use this?
The .ai format is most commonly used for Adobe Illustrator.
This format is not directly usable in flutter, it is also not used directly in application and web-development as to my best knowledge this a propriety format.
To use the asset in flutter you must export the asset from Adobe Illustrator to one of the formats supported in flutter such as .png or .jpeg
If you must use a vector based format, you could try using the asset as an .svg with the flutter_svg package
The .ai format is the extension of Adobe Illustrator, and it cant be opened in any other app or development platform, except Adobe Suit. So you can just export your file as.png or.jpeg.
You can do this by going to the menu on the top file<<export<export for screens, then you can save it in different file formats as mentioned.

Open generated file (Uint8list) in default application in Flutter

My application is generating excel and pdf reports. They are generated in Uint8list.
Is there a way to open such files in default application?
I tried open_file package, however, it requires a file path while my file is in memory.
same with url_launcher.
Also I tried saving the file then using open_file, but it doesn't work on web as file can't be saved.
I solved the issue by using printing.dat package. it has a PdfPreview that takes Uin8list and shows a preview with so many other options.

Flutter - multiple files for screens?

I'm currently learning Flutter development (as well as Dart). It's my first mobile programming language.
I'm curious - is there a way to split screens into .dart files, or do they all have to be in the same main.dart file?
The app I'm building will have a lot of pages, so I don't want to make one giant main.dart file with 20+ different pages.
Is Flutter the right choice if I'm trying to make a large application like this?
You can split your code in as many files as you want. It's encouraged to have as little code as possible in lib/main.dart and all the other code split into various files. The only limitation is that code in one file (library) can not access private members of other files.
See How to reference another file in Dart? for how to import other Dart files.
