flutter pub getInitialization requires 6 parameters, which are all str type:
| Name (in order) | Must | Description |
|---|---|---|
| clientId | Yes | Application.client_id |
| serverUrl | Yes | Casdoor Server Url, such as https://door.casdoor.com |
| organizationName | Yes | Organization name |
| appName | Yes | Application name |
| redirectUri | Yes | URI of Web redirection |
| callbackUrlScheme | Yes | URL Scheme |
final AuthConfig _config = AuthConfig(
clientId: "014ae4bd048734ca2dea",
serverUrl: "https://door.casdoor.com",
organizationName: "casbin",
appName: "app-casnode",
redirectUri: "http://localhost:9000/callback.html",
callbackUrlScheme: "casdoor"
);
flutter run -d chrome --web-port 9000
Download the WebView2 runtime from here and install it.
The WebView2 runtime is included in Windows 11 by default.
Add the package desktop_webview_window: ^0.2.3 inside dependencies to the pubspec.yaml file.
Modify the main function to look like the following:
void main(List<String> args) async {
WidgetsFlutterBinding.ensureInitialized();
if (runWebViewTitleBarWidget(args)) {
return;
}
runApp(const MyApp());
}
On the Web platform an endpoint needs to be created that captures the callback URL and sends it to the application using the JavaScript postMessage() method. In the ./web folder of the project, create an HTML file with the name e.g. callback.html with content:
<!DOCTYPE html>
<title>Authentication complete</title>
<p>Authentication is complete. If this does not happen automatically, please
close the window.
<script>
window.opener.postMessage({
'casdoor-auth': window.location.href
}, window.location.origin);
window.close();
</script>
Redirection URL passed to the authentication service must be the same as the URL on which the application is running (schema, host, port if necessary) and the path must point to created HTML file, /callback.html in this case, like callbackUri = "${_config.redirectUri}.html". The callbackUrlScheme parameter of the authenticate() method does not take into account, so it is possible to use a schema for native platforms in the code.It should be noted that when obtaining a token, cross domain may occur
For the Sign in with Apple in web_message response mode, postMessage from https://appleid.apple.com is also captured, and the authorization object is returned as a URL fragment encoded as a query string (for compatibility with other providers).
