QUESTION
I am writing a similar task manager app, i have some issues when working with BLoC:
- First, I create a Page to show all the task that have been added by pressing the FloatingActionButton() below.
- Next, when the user finished the form by hitting the FlatButton on the top right which is called SAVE, it will be submitted to Firestore, by the _submit() method in the JobForm class.
- NOTE: I also added some validator to validate the NameForm and the RatePerHourForm so it will show an error when they are null and they worked very well.
- I used a StreamBuilder() to update my JobPage() ( the first screen ), everywhen the data from Firestore changed.
- That was a summary of what I am trying to do.
BUT, when the user press the SAVE button, the Name Field and the ratePerHour Field is always empty even when i called onChanged: , in every TextField() to update them.
HERE IS MY flutter doctor:

I'm having a problem in my home_screen.dart file. I have a method called pullUserData() that is called in initState() but before pullUserData() is completely finished, the build method in home_screen.dart begins. This results in null values (auth and friendsList) being sent to NavDrawer() and FriendsFeed() in the build method of home_screen.dart.
How can I prevent NavDrawer() and FriendsFeed() from being called in the build method before initState() is completely finished? Should I use FutureBuilder?
User_data.dart handles gets the values for auth and friendsList.

Answered 2021-Jun-11 at 07:05There are couple of problems in your code but it will work.

Use the dependencies that you want, but if you aren't using analytics, leave it out. You have to import this first thing though firebasejs/8.3.0/firebase-app.js
QUESTION
I have a Flutter app that uses Firestore to store user data. I need help with retrieving the values stored in the 'friends' array. The image below shows the structure of my Firestore. As you can see, the 'friends' field is an array with two values: '123456' and '789123'.
I want to store these values in my variable called friendsList and I try to do this in getFriendsList(). To test and see if the 'friends' array values were stored in the friendsList variable, I use a print statement at the end of getFriendsList() to print the value of friendsList. But when I check my Console, Instance of 'Future' is printed and not the values of the 'friends' field.
How can I assign the values of the 'friends' array field from Firestore into my friendsList variable?
ANSWER
Answered 2021-Jun-07 at 07:07In the then callback, just assign your list to friendsList and change your friendsList to List type
