I implemented camera functionality within a Flutter app, so I’ll introduce the sample code.

Prerequisites

When Using Camera App

If you want to handle images taken with a camera app in Flutter rather than implementing camera functionality within the Flutter app, please refer to this article about handling images captured with camera app in Flutter.

Flutter packages Used

The Flutter packages used to implement camera functionality are as follows:

• camera | Flutter Package
• path | Dart Package
• path_provider | Flutter Package

Reference Information for Flutter Camera Functionality Implementation

I implemented it by referring to the following article from the official Flutter documentation:

• Take a picture using the camera - Flutter

The sample code on camera | Flutter Package was somewhat outdated code, so I didn’t refer to it. (As of February 28, 2020)

Flutter Camera Functionality Sample Code

Sample code that implements camera functionality in a Flutter app is published in the following GitHub Pull Request, so please take a look.

Side Note: Camera Functionality Not Available in iOS Simulator

This is a side note unrelated to Flutter, but camera functionality is not available in iOS Simulator, so I needed to test on iOS devices (iPhone, iPad).

Incidentally, camera functionality is available in Android Emulator, so you can test it even without an Android device.

That’s all about implementing camera functionality in Flutter from the Gemba.

That’s all from the Gemba.
