Flutter - Fit a video within a SizedBox

Question

I am using Chewie to display videos in my Flutter app. I have a full screen videos that looks like the image below:

I want to display the videos in the following format with a 1:1 aspect ratio.

Is it possible to achieve this automatically using Chewie without stretching or compressing the video or is there another way to achieve this. I tried various solutions I found online using AspectRatio, FittedBox and SizedBox.expanded widgets without any success.

Answer 1

Here's a combined approach that incorporates the best aspects of previous suggestions and addresses potential issues:

1. Manually Initialize VideoPlayerController:

Chewie's autoInitialize property might not always wait for the video's actual aspect ratio. To ensure control, manually initialize the VideoPlayerController:

final videoPlayerController = VideoPlayerController.network(yourVideoUrl);

Future<void> initializePlayer() async {
  await videoPlayerController.initialize();
  setState(() {});} // Rebuild the widget with the aspect ratio

Call initializePlayer() in your initState or a similar lifecycle method.

2. Use AspectRatio with videoPlayerController.value.aspectRatio:

Wrap the Chewie widget with an AspectRatio widget:

AspectRatio(
aspectRatio: videoPlayerController.value.aspectRatio,
child: Chewie(...),),// Your Chewie configuration

This ensures the Chewie widget respects the video's natural aspect ratio within the AspectRatio container. 3. Optional: Constrain Within a Container (if needed):

If you need further control over the video's placement, wrap the AspectRatio widget with a Container:

Container(
width: double.infinity,
height: double.infinity,
 child: AspectRatio(
aspectRatio: videoPlayerController.value.aspectRatio,
child: Chewie(...),),),

This ensures the video fills the available space while maintaining its aspect ratio within the container.
