Not able to load gallery images

[Shrulabh]

`import 'dart:io';

import 'package:flutter/material.dart';
import 'package:media_gallery/media_gallery.dart';
import 'package:permission_handler/permission_handler.dart';

class ListAppScreen extends StatefulWidget {
@OverRide
_ListAppScreenState createState() => _ListAppScreenState();
}

class _ListAppScreenState extends State {
List imageList = [];
_listMedia() {
Permission.storage.request().isGranted.then(
(value) {
if (value) {
print(value);
if (imageList.length == 0) {
fetchMediaFromPhone();
}
} else {
print(imageList.length);
Permission.storage.request();
}
},
);
print(imageList.length);
return imageList.length == 0
? Container(child: Center(child: CircularProgressIndicator()))
: Container(
child: GridView.builder(
gridDelegate:
SliverGridDelegateWithFixedCrossAxisCount(crossAxisCount: 3),
itemCount: imageList.length,
itemBuilder: (BuildContext context, index) {
return Container(
decoration: BoxDecoration(
border: Border.all(
width: 10,
color: Colors.black38,
),
),
child: Image.file(imageList[index]),
);
},
),
);
}

void fetchMediaFromPhone() {
MediaGallery.listMediaCollections(
mediaTypes: [MediaType.image],
).then((value) {
print(value);
for (MediaCollection collections in value) {
collections
.getMedias(
mediaType: MediaType.image,
take: 500,
)
.then(
(mediaPage) async {
for (var i in mediaPage.items) {
File mediaFile = await i.getFile();
if (!imageList.contains(mediaFile)) {
imageList.add(mediaFile);
}
print("item info of media type - ${mediaFile.path}");
}
setState(() {});
// break;
},
);
break;
}
});
}

void selectImage(BuildContext ctx) {
Navigator.of(ctx).pushNamed(
'/app',
);
}

@OverRide
Widget build(BuildContext context) {
return Scaffold(
body: Center(
child: _listMedia(),
),
);
}
}`

This the above code.
I am trying to display all the images in the gallery,
when the page loads up it is able to show only 4-5 images and then the app crashes. Please help..

Hi !

Do you have any log ? Maybe a memory issue.

Did you try the provided sample ? Does it work ?
