loadingdialog | Android普通样式加载框和精仿iOS加载框

My current code in lib/main.dart looks like this:

I would like to update the content of the TextView from "Loading.." to "Getting ready" after three seconds. Any advice on how to achieve this?

Thats my Loading Dialog.

when I run npm install or npm ci that seems to trigger a webpack build which produces tons of incorrect errors. All of them referring to not found dependencies which are definitely there. In addition, npm ci seems to trigger even more of these errors than npm install does.

When I run webpack build, the build runs just fine however. I am quite surprised by that behaviour as I don't seem to find any documentation on what's triggering this webpack run.

I'd like to better understand:

• what triggers webpack during npm install? (I would very much just like that to install dependencies)
• why does it show all these weird error messages?

I have installed:

• WSL 2 (Ubuntu 21.04) on Windows 11
• NPM 7.5.2
• Webpack ^5.65.0

Sample error output looks like this:

I am developing Android app which obtains information about restaurants from server and shows them in RecyclerView. When first package of information is obtained from server, everything works as expected, but, when I change search criteria and request new package of information from server, RecyclerView becomes blank. I used Toasts to debug what is coming from server and I am convinced that data is properly formatted. Also, variables that are used for accepting the data are also properly handled in code, according to my observations. Do you maybe know why my RecyclerView is empty when second package of data should be shown? Here is the code.

AfterLoginActivity.java

I am developing an App with the google recommended SingleActivity pattern. My scenario is: My App starts with the startDestination at HomeFragment. And If the user is not loggedIn I want to start from LoginFragment. My logic is I save loggedIn status in DataStore which is initially false. When My app starts launching. In my MainActivity, I observe that loggedIn status through ViewModel. Then I passed that status to a function. This is my function.

First of all thanks for your time. I'm trying to add a two option login in my app. One for a doctor and one for patient. I achieved to store both of them in realtime database as you can see below.

patient / doctor --> realtime database

As you can see, i have one tag ("isDoctor") with true o false for distinguish between both users. Wat i want to is to check the value of this "isDoctor" tag to send the user to the corresponding activity. If isDoctor is true i want to send the user to Doctor activity and if is a patient to the corresponding one. Is thinks that this checking should go in "State.Succes" once the user is sign in but i don't know how to perform it.

Here is my login code from RemoteDataSource class and from the login activity. I am using mvvm with flow for this project.

I am new to FLutter. I am using Bloc pattern as a design pattern. When clicked a button or text changed I successfully changed the event of the bloc.

But I need to get data when the page opens and bind it to a list. I don't know how can I change the bloc event to do that?

I've tried to add BlocBuilder in InitState but it didn't work.

here is my code.
