🧐 Question
Medium Analyzing StreamBuilder StreamBuilder ListView	Solve
Consider the below code: Analyze the given pseudocode and determine what will be displayed on the screen after the second emission of Stream (after 2 seconds). A: CircularProgressIndicator will be displayed. B: A ListView with 3 ListTile widgets, each displaying one item from the list ['Item1', 'Item2', 'Item3']. C: Text widget with 'No Items Available' will be displayed. D: A ListView with 0 ListTile widgets. E: The code will throw an error.
Medium Handling Push Notifications Push Notifications Application State	Solve
In a Flutter application, you are using the firebase_messaging package to handle incoming FCM (Firebase Cloud Messaging) push notifications. Consider the pseudocode below: In the _handleNotification method, the application is supposed to navigate to a details page if the action key in the notification data is equal to 'navigate'. However, this might not work as expected if the app is in the background or terminated state when the notification is received and the user clicked on it. How would you modify the _handleNotification method or handle the onMessage event to ensure that the navigation occurs when the user taps on the notification to open the app, no matter what state the app is in when the notification is received? A: Use _firebaseMessaging.onMessageOpenedApp to handle navigation when the user taps the notification to open the app. B: Use _firebaseMessaging.onLaunch to handle the navigation when the user taps the notification. C: Check the message.messageType and navigate only if it is 'opened'. D: Use _firebaseMessaging.onBackgroundMessage for handling navigation when the app is in the background. E: Use a GlobalKey<NavigatorState> to handle navigation in _handleNotification.
Medium Sliders Widgets	Solve
Dinance is a crypto finance mobile app. The app is built using Flutter and uses Sliders at multiple places. Review the following two snippets of Sliders used in the app. How will the Sliders be displayed? A: Slider X is displayed as a continuous slider with values {0.0, 0.25, 0.5, 0.75, 1.0} B: Slider X is displayed as a discrete slider with values {0.0, 0.25, 0.5, 0.75, 1.0} C: Slider X is displayed as a discrete slider with values {0.0, 0.33, 0.67, 1.0} D: Slider X is displayed as a discrete Slider with the values {0.0, 1.0, 2.0, 3.0, 4.0} E: Slider Y is displayed as a discrete Slider with the thumb rightmost F: Slider Y is displayed as a continuous Slider with thumb leftmost G: Slider Y is displayed as a discrete Slider with values {0.0, 0.25, 0.5, 0.75, 1.0} with thumb left most H: Slider Y is displayed as a continuous Slider with thumb rightmost

Easy Registration Queue Logic Queues	Solve
We want to register students for the next semester. All students have a receipt which shows the amount pending for the previous semester. A positive amount (or zero) represents that the student has paid extra fees, and a negative amount represents that they have pending fees to be paid. The students are in a queue for the registration. We want to arrange the students in a way such that the students who have a positive amount on the receipt get registered first as compared to the students who have a negative amount. We are given a queue in the form of an array containing the pending amount. For example, if the initial queue is [20, 70, -40, 30, -10], then the final queue will be [20, 70, 30, -40, -10]. Note that the sequence of students should not be changed while arranging them unless required to meet the condition. ⚠️⚠️⚠️ Note: - The first line of the input is the length of the array. The second line contains all the elements of the array. - The input is already parsed into an array of "strings" and passed to a function. You will need to convert string to integer/number type inside the function. - You need to "print" the final result (not return it) to pass the test cases. For the example discussed above, the input will be: 5 20 70 -40 30 -10 Your code needs to print the following to the standard output: 20 70 30 -40 -10
Medium Visitors Count Strings Logic	Solve
A manager hires a staff member to keep a record of the number of men, women, and children visiting the museum daily. The staff will note W if any women visit, M for men, and C for children. You need to write code that takes the string that represents the visits and prints the count of men, woman and children. The sequencing should be in decreasing order. Example: Input: WWMMWWCCC Expected Output: 4W3C2M Explanation: ‘W’ has the highest count, then ‘C’, then ‘M’. ⚠️⚠️⚠️ Note: - The input is already parsed and passed to a function. - You need to "print" the final result (not return it) to pass the test cases. - If the input is- “MMW”, then the expected output is "2M1W" since there is no ‘C’. - If any of them have the same count, the output should follow this order - M, W, C.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Flutter & Dart -test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Hoe wordt de test aangepast voor Fresher Flutter-ontwikkelaars?

De vragen voor junior Flutter-ontwikkelaars zullen van een iets eenvoudiger niveau zijn, en de vragen zullen gebaseerd zijn op beginners-/essentiële onderwerpen. Hier zijn enkele beginnersvaardigheden waarop de test zal worden gebaseerd:

Basisprincipes van Dart (controlestroom, functies, if-instructies, logische operatoren, for-lussen)
Basisprincipes van Dart Object-georiënteerd programmeren
Gegevensstructuren en verzamelingen in Dart
Basisprincipes van flutter
Navigatie tussen apps met meerdere schermen
Gebruik van ingebouwde widgets en styling
Gebruik van populaire bibliotheken van derden, zoals Material Design
Formulieren, invoerafhandeling en validatie
Het maken van asynchrone API-aanroepen om gegevens uit de cloud op te slaan en op te halen
Gebruik van JSON-formaat voor servercommunicatie.
Grondbeginselen van staatsmanagement

Kan ik meerdere vaardigheden combineren in één aangepaste beoordeling?

Ja absoluut. Aangepaste beoordelingen zijn opgezet op basis van uw functiebeschrijving en bevatten vragen over alle must-have vaardigheden die u opgeeft.

Heeft u functies tegen latere of proctoring op hun plaats?

We hebben de volgende anti-cheating-functies op zijn plaats:

Niet-googelbare vragen
IP Proctoring
Web Proctoring
Webcam Proctoring
Plagiaatdetectie
Beveilig browser

Hoe interpreteer ik testscores?

Het belangrijkste om in gedachten te houden is dat een beoordeling een eliminatietool is, geen selectietool. Een vaardighedenbeoordeling is geoptimaliseerd om u te helpen kandidaten te elimineren die niet technisch gekwalificeerd zijn voor de rol, het is niet geoptimaliseerd om u te helpen de beste kandidaat voor de rol te vinden. Dus de ideale manier om een beoordeling te gebruiken is om een drempelscore te bepalen (meestal 55%, wij helpen u benchmark) en alle kandidaten uit te nodigen die boven de drempel scoren voor de volgende interviewrondes.

Voor welk ervaringsniveau kan ik deze test gebruiken?

Elke ADAFACE -beoordeling is aangepast aan uw functiebeschrijving/ ideale kandidaatpersonage (onze experts van het onderwerp zullen de juiste vragen kiezen voor uw beoordeling uit onze bibliotheek van 10000+ vragen). Deze beoordeling kan worden aangepast voor elk ervaringsniveau.

Krijgt elke kandidaat dezelfde vragen?

Ja, het maakt het veel gemakkelijker voor u om kandidaten te vergelijken. Opties voor MCQ -vragen en de volgorde van vragen worden gerandomiseerd. We hebben anti-cheating/proctoring functies. In ons bedrijfsplan hebben we ook de optie om meerdere versies van dezelfde beoordeling te maken met vragen over vergelijkbare moeilijkheidsniveaus.
