When using camera package in Flutter it often happens that the picture rotation is messed up. If you are wondering what is Scaffold doing here than you can read my previous article How to design activity UI using Scaffold in Flutter ?.Below is the output from above code for using Row and Column widget. Fixed video and photo orientation upon save. Features: # Display live camera preview in a widget. (To know if I need to fix anything) One solution is to lock the app on portrait when you are on the recording page, and if you want to update the UI (button and other) listen to changes in device orientation. Here is the list of PR (only one of them has been merged so far and I have yet to get any answer from reviewers on the others): I created a branch with those 4 fixes merged together, I suggest you try this branch first and see if it works on your side: @Dwarfie Good to know it works properly :) To determine which values correspond to which orientations, first position the device in its default orientation (this is the orientation that the system first uses for its boot logo, or the orientation in which the hardware logos or markings are upright, or the orientation in which the cameras are at the top). I created a demo app that uses image streaming with tflite (TensorFlow Lite) plugin to achieve real-time object detection in Flutter. I remember now that I changed the parts of the camera example that I have used on a suggestion from Kenneth Li, and I am using a RoatedBox for the Camera Preview. In this example, build a list that displays two columns in portrait mode and three columns in landscape mode using the following steps: Build a GridView with two columns. I'll keep you updated. Switch between sensors easily. See also: BackdropFilter, a widget that applies ImageFilter to its rendering. Could you share the code of the widget where you have the CameraPreview? The OrientationBuilder widget will automatically compares Width and Height of device and in return us a True false Boolean value based on orientation. Flutter gives us a widget named as OrientationBuilder which is used to detect orientation in flutter apps. The PR request version has a squashed down preview in Portrait and rotated 90 degrees when phone is in Landscape, but this does actually capture the video in the right orientation. video_player: @escamoteur this is still broken. Flutter Camera plugin captures video rotated 90 degrees , Using the detailed example when I capture video in Landscape on an iPhone the preview is in Portrait aspect ratio with video rotated 90 The landscape mode preview shown at screen on smartphone is the same like portrait view, it is rotaded 90º. Intro. All the languages codes are included in this website. Adding SystemChrome.setPreferredOrientations() to my initState() & dispose() functions solved this problem for me. Any idea when the PR will get released ? and wrap body like this, you can reference full code at ; ImageFiltered, a widget that applies ImageFilter to its children. That’s it. Successfully merging a pull request may close this issue. And it is quite possible it will only work well only with the 4 fixes together. There are multiple solutions for this (e.g. I don't know when the PR will be reviewed. Output . The images stay vertical and don't rotate the 90degrees with the phone. Flutter has built-in function SystemChrome.setPreferredOrientations that allows us to set orientation of application. has do great work and provide great feature you can reference his source code or fork directly. Please don't hesitate to have a look at the PRs and leave comments or suggestions to push the review process. Having the wrong aspect ratio will lead to a weirdly distorted image (as if it was squashed or stretched). Using Stack widget, CameraPreview and CustomPaint widgets are positioned to draw rects of the detected object over the camera preview. Conclusion Using the current version of the camera plugin the Camera Preview fills the whole screen when the phone is in Portrait, and gets rotated when the phone is rotated.
