Flutter Desktop Auth - flutter

Question

As we all know desktop application has no auth support so any one can help me with this.
Future<http.Response> signUp(
String email,
String password,
) async {
final uri =
Uri.parse("https://identitytoolkit.googleapis.com/v1/accounts:signUp?key=$apiKey");
final headers = {
'Content-Type': 'application/json',
'Authorization': 'Bearer token',
};
Map<String, dynamic> body = {
"email": "xyz23#gmail.com",
"password": "password",
"returnSecureToken":true,
};
String jsonBody = json.encode(body);
final encoding = Encoding.getByName('utf-8');
http.Response response = await http.post(
uri,
headers: headers,
body: jsonBody,
encoding: encoding,
);
print(response.statusCode);
print(response.body);
jsonResponse = json.decode(response.body);
// box.write("token", jsonResponse['refreshToken']);
// oneTimeToken = jsonResponse['refreshToken'];
// print(oneTimeToken);
if (box.read('token') != null) {
Fluttertoast.showToast(
msg: 'Account Created Successfully',
toastLength: Toast.LENGTH_SHORT,
gravity: ToastGravity.CENTER,
timeInSecForIosWeb: 1,
backgroundColor: Colors.red,
textColor: Colors.white,
fontSize: 16.0
);;setState(() {
loading = false;
});
} else if (response.statusCode != 200) {
setState(() {
loading = false;
});
Fluttertoast.showToast(
msg: 'Account Already existing \n or missing data',
toastLength: Toast.LENGTH_SHORT,
gravity: ToastGravity.CENTER,
timeInSecForIosWeb: 1,
backgroundColor: Colors.red,
textColor: Colors.white,
fontSize: 16.0
);
}
return response;
}

Answer 1

Assuming you are NOT using OAuth 2.0 for your API, remove the authorization header from your sign up request and it should work.
final headers = {
'Content-Type': 'application/json',
//Remove this 'Authorization': 'Bearer token',
};
Try it out on the command line using your API key
curl --request POST \
'https://identitytoolkit.googleapis.com/v1/accounts:signUp?key=[YOUR_API_KEY]' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--data '{"email":"test#test.com","password":"password123"}' \
--compressed
