Is there a way to cache a network image that can be used later if there is no internet connection in flutter?
you can use also a package like path_provider to save the image to the device's storage, and then use Image.file constructor to load the image from storage when offline.

I have a flutter app that is a menu for a restaurant. Now the problem is that I want to get the pictures from firebase. Currently, if you open the app, the pictures take time to load and you can see that with your eyes, it is a bit annoying and not practical regarding bandwidth data usage.
Is there any chance I can cache the images when I get them from firebase and than appear instantly? I request the links of the images once the page is open using a future and display them with a CachedNetworkImageProvider() with the image URL but that still takes time to load the images. Is there a way to download all the data in the firebase at once when you open the app and not check every time you open the app?
for all apps that require fetching images from a remote location, what i have been doing so far is download the image locally and use the local image instead of the remote one if it exists locally, from my knowledge cachedNetworkImage only caches the image after fetching when the app is currently running and refetches the image when the user restarts the app.
Please if you do find another way to cache images that would be cool and remove a lot of boiler plate code, please do post it, thanks.
I am making a flutter app which loads about 700+ image from Cloud Storage through Firebase. Though, I am using pagination, the app still crashes sometimes on low end devices(does not crash on emulator). I have already compressed all my images, still sometimes it crashes. Is there a way to compress images when we load them from firestore to display only low quality thumbnails. It's a wallpaper app. So what I want to do is, display low quality images when loading all of them to reduce work load on the device and then use the original quality when setting them as wallpaper.
Note: I assume you're loading the images from Cloud Storage through Firebase, and not from Firestore itself. Firestore is a document database, while Cloud Storage is used for storing files. While both are part of Firebase, it's best not to confuse them.
There is no built-in functionality to generate thumbnails in Firebase or Cloud Storage. But there is an extension to resize images that you can enable, and that will then generate a thumbnail (or your specification) when new images are uploaded.
I found a way to display live camera on a container(). But I want to display gallery on Container() in app and control like photo example.
Is it possible in flutter ?
I'm not sure it would be possible to implement this but one things I have thought of is to request External Storage Access and maybe get the directory where all photo are stored and display the from File. However, this approach may need to a lot exceptions thrown.
I normal image_picker invokes the native channel to be able show the Android Native UI and same for iOS.
I have an application that uses a lot of images. I would like to store these images outside the ios/android device. I decided to store some of the images in firebase storage. How can I get images using storage? Like this
Image.asset(brand.model[0].model_image[index].image,
fit: BoxFit.fill),
Its better to store all these images in your app directory it will increase your app size but the images will load faster as they will be in the app itself plus help in reducing the data usage for the user as the app will not download the images on app launch but still if you want to keep the images in a outside server Firebase Storage will be the best use.
You can keep the assets separately in a folder called assets and you can use that from there. The only thing you need to do is specify the path in pubsec.yaml file to access the images.
I would always do it like.
assets
|_____images
|_____svgs
|_____audios
Hope this will help you to keep it organized.
I'm also into Flutter and Firebase, trying to keep the actual application as small as possible. I could write everything out right here, but the creators of FlutterFire have a website that explains every step in detail. This link below will direct you to the first step of using cloud storage.

I'm creating a Flutter App and I have to use about 600 PNG images (totalling 75 MB) I have tried adding the images folder and use it directly and the APK exceeded 100 MB size! how can I do this and avoid this huge APK size? Thanks in advance! :)
I would suggest you to use a cloud storage service like firebase,azure,google-cloud or any other simple server.
Then use CachedImage or Network Image widget and fetch them from the url. This is the best way to get large number of images with just less size of app
For such a large amount of images I would suggest you to use cloud storage as Krish told you before. In your case that you want your qpp to work offline you could still save some images in your assets folder and some in the cloud so the appa could be still usable and in a smaller size
