From asset bundle
You can also consider using local assets for placeholders.
First, add the asset to the project’s pubspec.yaml file
(for more details, see Adding assets and images):Then, use the FadeInImage.assetNetwork() constructor:
<code_start>FadeInImage.assetNetwork(
placeholder: 'assets/loading.gif',
image: 'https://picsum.photos/250?image=9',
),<code_end>

<topic_start>Play and pause a video
Playing videos is a common task in app development,
and Flutter apps are no exception. To play videos,
the Flutter team provides the video_player plugin.
You can use the video_player plugin to play videos
stored on the file system, as an asset, or from the internet.warning Warning
At this time,
the video_player plugin doesn’t work with any desktop platform.
To learn more, check out the video_player package.On iOS, the video_player plugin makes use of
AVPlayer to handle playback. On Android,
it uses ExoPlayer.This recipe demonstrates how to use the video_player package to stream a
video from the internet with basic play and pause controls using
the following steps:<topic_end>
<topic_start>
1. Add the video_player dependency
This recipe depends on one Flutter plugin: video_player.
First, add this dependency to your project.To add the video_player package as a dependency, run flutter pub add:<topic_end>
<topic_start>
2. Add permissions to your app
Next, update your android and ios configurations to ensure
that your app has the correct permissions to stream videos
from the internet.<topic_end>
<topic_start>
Android
Add the following permission to the AndroidManifest.xml file just after the
<application> definition. The AndroidManifest.xml file is found at
<project root>/android/app/src/main/AndroidManifest.xml.<topic_end>
<topic_start>
iOS
For iOS, add the following to the Info.plist file found at
<project root>/ios/Runner/Info.plist.warning Warning
The video_player plugin can only play asset videos in iOS simulators.
You must test network-hosted videos on physical iOS devices.<topic_end>

3. Create and initialize a VideoPlayerController
Now that you have the video_player plugin installed with the correct
permissions, create a VideoPlayerController. The
