001 Dart Overview En Subtitles

At 00:00:00,920, Character said: In the last section, we g***t a quick overview of how this course is organized and we ended up saying

2
At 00:00:05,150, Character said: that will first do a deep dive into the language itself and then eventually shift over to studying flutter

3
At 00:00:11,070, Character said: before we move on to our first application.

4
At 00:00:12,770, Character said: I want to give you a quick overview of DART itself so that you have some more context on the language.

5
At 00:00:18,260, Character said: So let's take a look at a diagram that's going to summarize a few important concepts about DART.

6
At 00:00:23,630, Character said: So in this diagram, we're going to take a look at four different important features of Dart.

7
At 00:00:28,220, Character said: First off, Dart is a object oriented programming language with an object oriented language.

8
At 00:00:33,530, Character said: We spend a lot of time thinking about how to model logic in our application.

9
At 00:00:37,310, Character said: Using objects in dart, objects are referred to as classes.

10
At 00:00:42,710, Character said: If you've never worked with an object oriented programming language before or don't know what the term

11
At 00:00:46,910, Character said: class refers to, that's completely OK.

12
At 00:00:49,640, Character said: We're going to do a deep dive on object oriented programming inside this course.

13
At 00:00:53,960, Character said: Second, DART is a statically typed language similar to C++, C Sharp or Java.

14
At 00:01:00,440, Character said: For reference, languages like, say, JavaScript or Ruby are examples of it dynamically typed languages.

15
At 00:01:07,520, Character said: We will of course, discuss static typing quite a bit throughout this course.

16
At 00:01:11,000, Character said: But for now, just imagine that in DART we have to make sure that any given variable can only contain

17
At 00:01:16,520, Character said: data of a single type like, say, an integer or a string.

18
At 00:01:20,840, Character said: If you've never worked with a statically typed language before or if you feel a little bit intimidated

19
At 00:01:25,940, Character said: by types, I really recommend you not worry one bit.

20
At 00:01:30,350, Character said: The type system and DART is extremely flexible for beginners.

21
At 00:01:35,050, Character said: Third, Dart has a sea style syntax, so in general, it's going to look very similar to C, C sharp

22
At 00:01:42,280, Character said: or JavaScript or even Java, you will probably not be seeing a lot of strange symbols inside your code.

23
At 00:01:48,250, Character said: Most of the code that you and I are going to write is going to look quite legible in my personal opinion.

24
At 00:01:53,710, Character said: Finally, Dart has multiple runtime environments, that means to say that we can somehow execute dart

25
At 00:01:59,500, Character said: code in the browser from our command line or with mobile apps when ran in the browser, Dart first gets

26
At 00:02:06,230, Character said: transpired into plain JavaScript code and we will see a good example of this and one of the apps that

27
At 00:02:11,470, Character said: we're going to work on later in the course.

28
At 00:02:14,140, Character said: When ran from the command line as a stand alone program, Dart is executed in something called the Dart

29
At 00:02:19,450, Character said: VM or the Dart Virtual Machine.

30
At 00:02:22,360, Character said: Finally, on a mobile device, Dart is first compiled into machine code.

31
At 00:02:26,590, Character said: So your mobile device doesn't ever touch a snippet of pure dart.

32
At 00:02:30,160, Character said: It works directly with machine code.

33
At 00:02:32,940, Character said: OK, so in the section, we g***t a very high level view on a couple of different aspects of dirt, let's

34
At 00:02:38,310, Character said: now continue in the next section and start working on our first tiny little application.
