View Last 3 Most Recent Images Taken With Camera In Flutter - flutter

Question

I would like to display last 3 images in the camera roll/gallery/photos from my app. How do I achieve this in Flutter?
Any ideas?
Suppose I want to see the latest images in the DCIM folder. How do we do this?

Answer 1

I hope what you're looking for will be solved by using this package photo_gallery

Answer 2

Never used this package before, but it seems to fit your needs.
Try to use media_picker_widget as its supports presenting specific amount of images from different albums using custom widgets.
Check out the official example:
import 'package:flutter/material.dart';
import 'package:media_picker_widget/media_picker_widget.dart';
void main() {
runApp(const MyApp());
}
class MyApp extends StatelessWidget {
const MyApp({Key key}) : super(key: key);
#override
Widget build(BuildContext context) {
return MaterialApp(
title: 'Media Picker',
theme: ThemeData(
primarySwatch: Colors.green,
),
home: const MyHomePage(),
);
}
}
class MyHomePage extends StatefulWidget {
const MyHomePage({Key key}) : super(key: key);
#override
_MyHomePageState createState() => _MyHomePageState();
}
class _MyHomePageState extends State<MyHomePage> {
List<Media> mediaList = [];
#override
void initState() {
super.initState();
}
#override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: const Text('Image Picker'),
),
body: previewList(),
floatingActionButton: FloatingActionButton(
child: const Icon(Icons.add),
onPressed: () => openImagePicker(context),
),
);
}
Widget previewList() {
return SizedBox(
height: 96,
child: ListView(
scrollDirection: Axis.horizontal,
shrinkWrap: true,
children: List.generate(
mediaList.length,
(index) => Padding(
padding: const EdgeInsets.all(8.0),
child: SizedBox(
height: 80,
width: 80,
child: Image.memory(
mediaList[index].thumbnail,
fit: BoxFit.cover,
),
),
)),
),
);
}
void openImagePicker(BuildContext context) {
// openCamera(onCapture: (image){
// setState(()=> mediaList = [image]);
// });
showModalBottomSheet(
context: context,
builder: (context) {
return MediaPicker(
mediaList: mediaList,
onPick: (selectedList) {
setState(() => mediaList = selectedList);
Navigator.pop(context);
},
onCancel: () => Navigator.pop(context),
mediaCount: MediaCount.multiple,
mediaType: MediaType.image,
decoration: PickerDecoration(
actionBarPosition: ActionBarPosition.top,
blurStrength: 2,
completeText: 'Next',
),
);
});
}
}
