Dart library for RICOH THETA Mobile and Desktop Developers
Based on THETA Web API v2.1. For information on connecting the camera and testing the camera API with a command line tool, see RICOH THETA API HTTP Community Tests README.
This is for education and testing use only and should not be used for production. Only a portion of the API has been implemented. We are using this library to document usage of the API and show prototypes of concepts such as displaying thumbnails. We are not to using the library to build production apps.
This project is not connected to any official RICOH project.
Installation
- save the packages directory to the root directory of your Flutter or Dart app
- Add the following dependency to
pubspec.yaml
dependencies:
theta:
path: packages/theta- import the library
import 'package:theta/theta.dart';Install from GitHub
Alternately, you can install the package automatically from GitHub without
having to copy the files into your project. To automatically install from
GitHub, add the following to your pubspec.yaml file.
dependencies:
theta:

ref: mainExample Command Line Use
...
yourFunction() async {
print(await Camera.info);
}Full Program Example
A fully working program showing the main top-level function where the Dart
app starts working.
import 'package:theta/theta.dart';
void main(List<String> args) async {
print(await Camera.info);
}Assuming the test program is in ./bin/test_temporary.dart, you can run the program and
see the output with:
> dart .\bin\test_temporary.dart
{manufacturer: RICOH, model: RICOH THETA SC2, serialNumber: 20001005, firmwareVersion: 01.51, supportUrl: https://theta360.com/en/support/, gps: false, gyro: true, endpoints: {httpPort: 80, httpUpdatesPort: 80}, apiLevel: [2], api: [/osc/info, /osc/state, /osc/checkForUpdates, /osc/commands/execute, /osc/commands/status], uptime: 2088, _wlanMacAddress: 58:38:79:2b:ad:c5, _bluetoothMacAddress:
6c:21:a2:47:d9:05}Formatting Camera Output for Humans to Read
You can format the output with the following conversion where map is the output from info.
JsonEncoder.withIndent(' ').convert(map)Example:
import 'dart:convert';
import 'package:theta/theta.dart';
String pretty(map) {
return (JsonEncoder.withIndent(' ').convert(map));
}
void main(List<String> args) async {
print(pretty(await Camera.info));
}Your output will now have nice indents.

Full code for demo above from the main.dart file.
Note that you likely want to break up your program into separate files and use state management such as BLoC or Provider in your actual app. The example uses a stateful widget to show the basic use of the library.
