Flutter How to save Image file to new folder in gallery?

Question

I want to save the image in the gallery after I get the file from the camera, how to create a new directory and save the image file that we have obtained from the camera?

Answer 1

You need to save the image into external storage directory for showing the image on gallery. Instead of getting temporary directory, obtain external storage directory.

final directory = await getExternalStorageDirectory();

You need to provide the permission on AndroidManifest.xml file of your android/app/src/main folder

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

then let's say that you want to create a folder named MyImages and add the new image to that folder,

final myImagePath = '${directory.path}/MyImages' ;
final myImgDir = await new Directory(myImagePath).create();

then write to the file to the path.

var kompresimg = new File("$myImagePath/image_$baru$rand.jpg")
  ..writeAsBytesSync(img.encodeJpg(gambarKecilx, quality: 95));

for getting the number of files, just obtain the files to a list and check the length of the list

var listOfFiles = await myImgDir.list(recursive: true).toList();
var count = countList.length;
