Building widgets with Hive box data - flutter

Question

I was building my Widgets from a list that was predefined in a file of MyClass I created. This worked but I wanted to be able to store persisted data for adding a Boolean favorite field.
I created the Hive Types/Fields for my class, generated the type adapters, and successfully loaded the Hive box on first run of the app, and I can print values to the console, so I know the data is all there and correct.
In the class I have, name, image url path to asset image and a favorite field.
Before when I was using the list to get my data I was able to get the image URL like this:
Expanded(child: Image.asset(widget.MyClass.imageURL)),
Now I want to get this from the Hive box
Box<MyClass> box = Hive.box<MyClass>('myClassBox');
//This is where I am stuck
Expanded(child: Image.asset(box.???)),
I tried box.values.where and box.get() to then get to imageURL field. But get requires a key, which I don't have to pass it from
Widget build(BuildContext context)
And I then have the same issue when trying to access the favorite field, which I am using the Favorite Button package (favorite_button 0.0.4). And I will then update the true/false value based on the button being tapped.
If someone can point me in the right direction that would be great.
Thanks.
Edit:
Here is the Widget:
Widget build(BuildContext context) => GestureDetector(
onTap: () => Navigator.of(context).push(MaterialPageRoute(
builder: (context) => TaskPage(job: widget.job), //Need to get data from Hive now
)),
child: Container(
padding: const EdgeInsets.all(16),
height: 100,
decoration: BoxDecoration(
borderRadius: BorderRadius.circular(16),
),
child: Row(
children: [
Expanded(flex: 3, child: buildText()),
Expanded(child: Image.asset(widget.job.imageUrl)),//Need to get data from Hive now
GestureDetector(
child: Icon(
widget.job.fav ? Icons.favorite : Icons.favorite_border, //Need to get data from Hive now
),
onTap: () {
// add/remove from favorites list
}
),
],
),
),
);
Second Edit: Here is the same code after implementing the suggestion given
Widget build(BuildContext context) => GestureDetector(
onTap: () => Navigator.of(context).push(MaterialPageRoute(
builder: (context) => TaskPage(job: Hive.box<Job>('jobBox').get(context)), //This bit is still broken so I need to look at this
)),
child: Column(
children:
Hive.box<Job>('jobBox').values.toList().map(
(elementList) => Container(
padding: const EdgeInsets.all(16),
height: 100,
decoration: BoxDecoration(
color: white,
borderRadius: BorderRadius.circular(16),
),
child: Row(
children: [
Expanded(flex: 3, child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text(
elementList.name,
style: TextStyle(fontWeight: FontWeight.w500, fontSize: 20),
),
SizedBox(height: 10),
//Text('Num tasks in job'),
],
)),
Expanded(child: Image.asset(elementList.imageURL)),
GestureDetector(
child: Icon(
elementList.fav
? Icons.favorite
: Icons.favorite_border,
color: elementList.fav ? Colors.red.shade200 : Colors.grey,
),
onTap: () {
//To do
}
// )
),
],
),
),
)
.toList(),
),
);

Assuming that you have only 1 data in the box, you can access that stored data like this.
Box<MyClass> box = Hive.box<MyClass>('myClassBox');
if(box.isNotEmpty) {
final data = box.values.first;
// use data
} else {
// empty state
}
Hive values could have keys, depending on how you use it. If you used box.put(key, value), you can use box.get(key) to work with keys and values.
If you used box.add(value), it stores the data with auto assigned indexes starting from 0. So you can usebox.getAt(index) to get a data with index.
