RTE

-
Stands for "Runtime Environment." As soon as a software program is executed, it is in a runtime state. In this state, the program can send instructions to the computer's processor and access the computer's memory (RAM) and other system resources.
When software developers write programs, they need to test them in the runtime environment. Therefore, software development programs often include an RTE component that allows the programmer to test the program while it is running. This allows the program to be run in an environment where the programmer can track the instructions being processed by the program and debug any errors that may arise. If the program crashes, the RTE software keeps running and may provide important information about why the program crashed. When you see the name of a software program with the initials "RTE" after it, it usually means the software includes a runtime environment.
Program:
public class RTE{
public static void main(string args[]){
rt.gc();               //for garbage collection
//or
system.gc();       //for garbage collection
}
}

Dart: Functions

  Functions Functions let you package multiple related lines of code into a single body that you can summon to avoid repeating those lines of code throughout your Dart application: A function consists of a return type , a function name , a parameter list in parentheses, and then a function body enclosed in braces. The code you're turning into the function goes inside the braces. When you call the function, you pass in arguments that match the types of the parameters of the function. Write a new function in DartPad that will just check to see if a given string is banana. bool isBanana( String fruit) { return fruit == 'banana' ; } The function uses return to return a bool value determined by the argument passed to the function. This function will always return the same value for any given input. If a function does not need to return a value, you can set the return type to void , such as for the main function.   Optional Parameters If a parameter to a funct

Firebase Cloud Messaging

  what are push notifications? Push Notifications are a sort of pop-up messaging medium that alerts app users to what's going on in the app. They are also an important way to amplify user engagement in your app. For example, say a user forgets about the app once they have installed it. Then you can use push notifications as a mechanism to regain and retain their interest. Push notifications also help drive traffic to your app. Firebase Cloud Messaging is a service offered by Firebase which lets you send these notifications to your users. You can set up various configurations to send different notifications to different audiences based on time and routine. Because of all these benefits, we are going to use it to send notifications to our Flutter app. Step 1: Create a Flutter Project First, we are going to create a flutter project. For that, we must have the Flutter SDK installed in our system. You can find simple steps for flutter installation in the official documenta
