PageView.builder constantly re-caches static images
I have a music playing screen where swiping on the album art plays the next track. I am using PageView.builder to populate the list of tracks.
I enabled the checkerboardRasterCacheImages flag and screencap'd a video. Here's the link: https://streamable.com/1oi6h
The issue is that album image is constantly being re-cached which causes dropped frames which is resulting in sub-60 fps scenes.
I tried wrapping my widget with a RepaintBoundary widget but it still re-caches the images.
Also tried removing the background blur.
AspectRatio(
aspectRatio: 1.0 / 1.0,
child: Container(
width: media.size.width,
child: PageView.builder(
controller: _pageController,
onPageChanged: (int idx) {
if (idx < _pageController.page)
prev();
else
next();
},
itemCount: widget.playlist.length(),
itemBuilder: (context, index) {
return Padding(
padding: media.padding.add(
EdgeInsets.all(40)),
child: DecoratedBox(
decoration: new BoxDecoration(
image: DecorationImage(
image: widget.playlist
.get(index)
.albumArt,
fit: BoxFit.fill,
),
boxShadow: [
new BoxShadow(
color: Colors.black
.withOpacity(
0.5),
offset: new Offset(2.0, 2.0),
blurRadius: 5.0,
spreadRadius: 5.0)
]
),
),
);
}),
),
),
I'm expecting since it is a static image, it shouldn't re-cache every frame. Also, this is my first app and first time posting here so if more info/code is needed please don't hesitate to ask for whatever is needed.
Thanks.
