## 1. Introduction to Programming
Programming is the process of writing instructions for a computer to perform a task. Let's dive into the basics of programming!
## 2. Variables and Data Types
In Dart, variables store data. Data types include int, double, String, and bool.
```dart
void main() {
// Variable declaration and initialization
int age = 25;
double height = 5.9;
String name = "John";
bool isStudent = true;
// Outputting values
print("Name: $name, Age: $age, Height: $height, Student: $isStudent");
}
```
## 3. Control Flow
Use if statements for decision-making and loops for repetition.
```dart
void main() {
// Control flow with if statement
bool isRaining = true;
if (isRaining) {
print("Bring an umbrella!");
} else {
print("Enjoy the weather!");
}
// Looping with for loop
for (int i = 0; i < 5; i++) {
print("Count: $i");
}
}
```
## 4. Functions
Functions are blocks of code that perform a specific task. They can take parameters and return values.
```dart
void main() {
// Function declaration and call
greet("Alice");
}
// Function definition
void greet(String name) {
print("Hello, $name!");
}
```
## 5. Lists/Arrays
Lists store multiple items. Access and modify list elements.
```dart
void main() {
// List declaration and initialization
List fruits = ["Apple", "Banana", "Orange"];
// Accessing list elements
print("First fruit: ${fruits[0]}");
// Modifying list
fruits.add("Grapes");
print("Fruits: $fruits");
}
```
## 6. User Input
Get user input and use it in your program.
```dart
void main() {
// User input
print("Enter your name:");
String userName = stdin.readLineSync();
print("Hello, $userName!");
}
```
## 7. Setting Up DartPad
1. Open your web browser.
2. Go to [DartPad](https://dartpad.dev/).
## 8. Writing Your First Dart Program
Open DartPad and write your first Dart program.
```dart
void main() {
print("Hello, DartPad!");
}
```
Click "Run" to see the output.
## 9. Data Types in Dart
Understand Dart data types.
```dart
void main() {
int age = 25;
double height = 5.9;
String name = "John";
bool isStudent = true;
}
```
## 10. Control Flow in Dart
Use if statements and loops in Dart.
```dart
void main() {
bool isRaining = true;
if (isRaining) {
print("Bring an umbrella!");
} else {
print("Enjoy the weather!");
}
for (int i = 0; i < 5; i++) {
print("Count: $i");
}
}
```
## 11. Functions in Dart
Learn how to declare and use functions in Dart.
```dart
void main() {
greet("Alice");
}
void greet(String name) {
print("Hello, $name!");
}
```
## 12. Lists in Dart
Explore lists in Dart.
```dart
void main() {
List fruits = ["Apple", "Banana", "Orange"];
print("First fruit: ${fruits[0]}");
fruits.add("Grapes");
print("Fruits: $fruits");
}
```
## 13. User Interaction in Dart
Get user input and display results.
```dart
void main() {
print("Enter your name:");
String userName = stdin.readLineSync();
print("Hello, $userName!");
}
```
## 14. Simple Exercises
Try these simple exercises to reinforce your learning:
1. Write a program to calculate the sum of two numbers.
2. Create a list of your favorite movies and print them.
