Some questions regarding authentication.

[SupremeDeity]

First of all, i have not used a reddit api before.

I want to create a reddit client as practice for creating flutter apps, the questions i have are:

1. Can i just use "localhost:3000" for the redirect uri.
2. The part in the example regarding fetching the auth code is left upto the user. I saw a closed issue regarding this which used uni_links and url_launcher. I am going to try using the webview plugin instead. Is this a good idea?
3. How would i refresh my authentication? How do i check if my auth code expired? Do i just run the refresh method from auth.dart everytime my code expires?

Sorry that some of these come of as a bit noobish but i will keep experimenting and if possible provide a complete example after i am done for those that come looking for it afterwards.

The first two parts have been solved by me:

1. I have to use deep link/uni-link
2. I ended up using url_launcher and uni_link

These are some issues i still have:

1. I still dont know how i can verify my session, instantiate my reddit instance etc.

I'll be completely honest, I'm not 100% sure about refreshing authentication tokens. Calling refresh() should do the trick, but when in doubt, referring to the PRAW documentation should get you on the right path (DRAW shares a lot of the same logic as PRAW for authentication). Maybe this will help?

As a followup to this, for whoever wants to find a answer. This is mainly for Installed Flow:

1. You should go through my comment and read on the second method. It explains a lot.

2. After reading on that, look up: url_launcher and uni_links. This is for getting the refresh token for the first time.

• redirect_url: The url you get redirected to AFTER the authentication on the webpage is completed. This is very important. Read below for more info.

• url_launcher: For launching the url you got with reddit.auth.url()

• uni_link: Use the deep link to create a scheme like: myapp://auth, this also needs to be your redirect_url. Uni_link will then catch, whenever you get redirected to this link, and bring you back to the app.

3. Save the credentials somewhere with SharedPreferences or some other package. I would recommend checking out how its done on the Web Authentication Flow on the readme.

4. Use the credentials with Reddit.restoreInstalledAuthenticatedInstance() instead of the Reddit.createInstallFlowInstance(). Both these methods return a Reddit Instance.

Note: The credentials contains the refresh token, you need to save the entire credentials.

@bkonyi i would recommend you reference this in your readme in the installed flow section.
