simple_camera_windows

A simple plugin with basic camera API to access and capture picture from the camera on windows platform

Getting Started

This project is equiped with the basic activities to access general functionalities of camera on windows platform using some defined API's using Flutter Method Channel.

This package is built with non granular approach, so make sure if the package meets your requirements before implementation because this package is above the rope of fray, due to its limited access to the camera functionality.

Here are the supported functions exposed by the simple_camera_windows package.

• startCamera(): Aims to access and display the camera preview inside a new window.

• stopCamera(): After done with the camera, this function is used to terminate the camera access.

• captureFrame(): While accessing the camera, call this function to capture a frame, the function returns the frame with typed as Uint8List?. you can then use the response as per your needs, you can convert the response into Base64 or Image, please check for the detail instruction to convert Uint8List to Base64 or Image.

Project structure

This template uses the following structure:

• lib: Contains the Dart code that defines the API of the plugin, and which calls into the native code using MethodChannels.

• platform folders (linux, windows, etc.): Contains the build files for building and bundling the native code library with the platform application.

Building and bundling native code

The pubspec.yaml specifies plugins as follows:

  plugin:
    platforms:
      linux:
        pluginClass: SimpleCameraWindowsPlugin
      windows:
        pluginClass: SimpleCameraWindowsPluginCApi

This configuration invokes the native build for the various target platforms and bundles the binaries in Flutter applications..

A plugin can have both FFI and method channels:

  plugin:
    platforms:
      some_platform:
        pluginClass: SomeName
        ffiPlugin: true

The native build systems that are invoked by FFI (and method channel) plugins are:

• For Windows: CMake.
  • See the documentation in windows/CMakeLists.txt.

Invoking native code

Use MethodChannel provided by flutter to invoke native functions defined in the files.

example: final methodChannel = const MethodChannel('dev.spantik/camera');

then: await methodChannel.invokeMethod('initializeCamera');
