How to display image from firebase storage into widget?










1















I want to display the image saved in firebase storage into a widget that shows profile picture in my screen.
Currently I am able to get the download url but not sure how to make use of that url that will display the image into the widget. Here's the code that displays the profile picture UI that I want to update with image from firebase (ie inside ClipOval widget)



@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text('Edit Profile'),
actions: <Widget>[
new Center(child: new Text('SAVE')),
],
),
body: new Stack(
children: <Widget>[
Positioned(
width: 410.0,
top: MediaQuery
.of(context)
.size
.height / 25,
child: Column(children: <Widget>[
Container(
child: user.profilePhoto == ""
? Image.asset('icons/default_profile_icon.png',
height: 110.0)
: ClipOval(
child: _imageFile == null ? Image.asset('icons/default_profile_icon.png', height: 110.0,)
:Image.file(_imageFile,fit: BoxFit.cover,
width: 110.0,
height: 110.0,)
),
),


This is how I am fetching image from firebase storage which returns download url:



 displayFile(imageFile) async 

String fileName = 'images/profile_pics/' + this.firebaseUser.uid + ".jpeg";
var data = await FirebaseStorage.instance.ref().child(fileName).getData(10000000);
var text = new String.fromCharCodes(data);
return new NetworkImage(text);




Do I need to use NetworkImage or cached-network-image or cache_image widget to achieve this ?

          • Yes that's what I was looking for. There's a minor issue though, now whenever I select an image from camera or gallery, it's not immediately reflected inside ClipOval. If I go to other screen and then come back, then I see the widget updated with latest picture. Would you know why this could be happening ? I am expecting to see the image capture or selected from gallery to be shown immediately. @Günter Zöchbauer

          • Yes that's what I was looking for. There's a minor issue though, now whenever I select an image from camera or gallery, it's not immediately reflected inside ClipOval. If I go to other screen and then come back, then I see the widget updated with latest picture. Would you know why this could be happening ? I am expecting to see the image capture or selected from gallery to be shown immediately. @Günter Zöchbauer

          I think displayFile method is similar to what you suggested. How do I make use of it inside ClipOval widget so that the image will be displayed ? @Günter Zöchbauer

          Sorry, I don't understand your question. If you want to download the image yourself (.getData(...)), then you need MemoryImage instead of NetworkImage.

          Sorry if I was not clear earlier.I was not sure how do I use the download url inside clipoval widget under build widget. If you see currently it uses Image.file that displays the image from camera and gallery but doesn’t persist. How do i use NetworkImage or the code you suggested inside clipoval that will display the image from storage from inside of clipoval ? @Günter Zöchbauer
