How to display all image formats in flutter? - flutter

I want to display a lot of types of images in flutter app (like format SVG, png, and jpg)
But I have a problem showing SVG images in my flutter app.
I'd used flutter-svg package to display SVG images, but it doesn't support png and jpg images. :(
How to resolve it?

Flutter SVG package is only for SVG images. For png and jpg you need to implement normal image display method.

you can use this code for accept all format:
(imageF.contains('svg') ? SvgPicture.network(image) : Image.network(image)),

adding svg image to splash screen flutter

I want to show a svg image in splash screen.
I tried flutter_native_splash package but it's only work with jpg & png. Is there any alternative way to add svg image to splash screen?
You could implement it manually for Android and iOS like described in the docs.
For Android you can use a tool like Respresso to convert your SVG to an Android vector drawable.
Xcode 12 and higher also supports SVG in storyboards as far as I know.

How to crop url image with Flutter?

I tried using a image-crooper in flutter, but they only for local image. How to crop the image with url image?
I'd like to introduce my developing package crop_your_image. You can convert downloaded image data into UInt8List and pass it to Crop widget. Then, it would show up cropping UI on the screen.
You can find a sample app which downloads images via URL and let user crop them.

How to convert PNG image to GIF in iPhone programmatically

How to picker some pictures from the library, and convert them to a gif?
There's ImageMagick for iPhone.Check Using ImageMagick to create animated GIFs on the iPhone.
Or search "ImageMagick for iphone" at Google
Check these Links
According to Apple,
Xcode automatically optimizes your PNG images using the pngcrush
utility shipped with the SDK. (You’ll find the program in the iPhoneOS
platform folders in /Developer. Run it from the command line with the
–iphoneswitch to convert standard PNG files to iPhone- formatted
ones.) For this reason,use PNG images in your iPhone apps where
possible as your preferred image format.
Better prefer to use PNG's for your image requirements

Hope this Helps
You can create a GIF using the ImageIO framework, which is part of the iOS SDK. You don't need ImageMagick or any other third-party library.
Look at this answer for code that uses ImageIO to create an animated GIF. If you don't want an animated GIF, just add a single image instead of a bunch of images.
As for picking images from the library, there are many questions about this already on stackoverflow. Just search for [iphone] pick image from library.

can we use .jpg format images for mobile applications I.e iphone and android

i am working on mobile application where i need to display a background image using css sprites. here is the problem image size is 1600px width and 480px height. when i convert this image to png the file size is 400kb. and in jpg format it is 80kb.
So, my question is whether can i use the jpg format image in mobile application. especially in iphone and android........?
Thanks in Advance....
Yes
We can use jpg files BUT it is preferred to use png files as they are very lightweight to use.So as far as mobile apps are concerned png are the ones used.
