Error handling in Dart involves handling exceptions and errors when the program encounters an unexpected situation.
This is crucial to make the program robust and user-friendly.
Dart uses 'try-catch' blocks to catch exceptions, with the 'on' keyword for specific types and 'catch' for all types.
Here , I am attaching one example of try and catch block with on keyword.
void main()
{
String userInput = "3,14";
try{
double num = double.parse(userInput);
print("Squre value is $userInput * $userInput");
}on FormatException catch (e){
print("You have inavalid input , Enter valid value and try agian");
print(e);
}
catch(e)
{
print("Somthing wrong happend in your output");
print(e);
}
}
In the above example you can see that we have use try , catch and on method to handle the error when it throw runtime.
