When I try to run images assets doesn't get properly loaded, I am getting an exception:
The following assertion was thrown resolving an image codec: Unable to load asset: /images/p8.png`
Some weeks ago it was working and now it stopped. I tried to run from different pc and mac too (with simulator) anв still no images can be loaded. Fonts instead are properly loaded.
This is how I load the images, they are rendered inside a GridView
Below is the code:
return new Expanded(
child: new GridView.count(
crossAxisCount: 2,
padding: const EdgeInsets.fromLTRB(16.0, 25.0, 16.0, 4.0),
children: <Widget>[
new MaterialButton(
onPressed: () {
Navigator.of(context).pushNamed('/biliardo');
},
child: new Column(
children: <Widget>[
new Image(
//parte importante, definire gli asset per trovarli più velocemnte
//si inseriscono nel pubspec.yaml
image: new AssetImage('/images/p8.png'),
height: 100.0,
width: 100.0,
),
new Text(
"BILIARDO",
style: new TextStyle(
color: (darkTheme) ? Colors.blue : Colors.black,
),
)
],
),
),
.....
);
pubsec.yaml file code:
flutter:
uses-material-design: true
assets:
- images/emptyBall.png

Get rid of the leading /
in your path to the png. It should be images/p8.png
.
Also, consider using the cleaner Image.asset
constructor, for example:
new Image.asset('images/p8.png', width: 100.0, height: 100.0)
