Using the http commands, such as GET and POST, the application receives information and executes commands. Below is a list of this project's button controls using the [THETA WebAPI](https://api.ricoh/docs/theta-web-api-v2.1/). + +## Button Controls + +* [Info](https://api.ricoh/docs/theta-web-api-v2.1/protocols/info/) +* [State](https://api.ricoh/docs/theta-web-api-v2.1/protocols/state/) +* [camera.takePicture](https://api.ricoh/docs/theta-web-api-v2.1/commands/camera.take_picture/) + +## http Package + +In order to use the http package, I first needed to download it and import it at the top of my file. All HTTP requests require a url. For example, this is the url for getting the info from the camera. + +``` +var url = Uri.parse('http://192.168.1.1/osc/info'); +``` + +Next, I created a header using a key-value pair. + +``` +var header = { + 'Content-Type': 'application/json;charset=utf-8'} +``` + +Finally, the http method is sent out and assigned to a variable called `response`. + +``` +var response = await http.get(url, headers: header); +``` + +At the moment, this application does not display any response to the screen, instead, the output is printed out to the console. + +![output](docs/output.png) + +## Take Picture 📷 + +The command for taking a picture differs slightly from the info and state buttons as we need to run `jsonEncode`. The url for taking the picture uses `/osc/commands/execute` as shown below. + +``` +var url = Uri.parse('http://192.168.1.1/osc/commands/execute'); +``` + +I created a map called `bodyMap` that stores the key-value pair from the camera. Next, I had to encode the map into Json, so I could pass it into my response. + +``` +var bodyMap = {'name': 'camera.takePicture'}; +var bodyJson = jsonEncode(bodyMap); +``` + +The response requires the url, but I also passed in the `bodyJson`. + +``` + var response = await http.post(url, headers: header, body: bodyJson); +``` + +As the response is a POST request, the application sends out information and takes a picture. + +![example picture](docs/screenshot.jpg) + +## JSON Decode + +To access certain properties in the state of the camera, the response from the camera needs to be decoded. After the response is decoded, a specific property, such as `batteryLevel`, can be accessed as a map. In the future, I can use this `batteryLevel` to update the state of the application. + +``` +var thetaState = jsonDecode(response.body); +var batteryLevel = thetaState['state']['batteryLevel']; +``` diff --git a/analysis_options.yaml b/analysis_options.yaml new file mode 100644 index 0000000..61b6c4d --- /dev/null +++ b/analysis_options.yaml @@ -0,0 +1,29 @@ +# This file configures the analyzer, which statically analyzes Dart code to +# check for errors, warnings, and lints. +# +# The issues identified by the analyzer are surfaced in the UI of Dart-enabled +# IDEs (https://dart.dev/tools#ides-and-editors).
