Error handling in File operations in Dart is crucial and vital for building robust applications. Like Exception handling We also use try and catch for file handling as well. Example If we do not find a file the directory to write than we can use try and catch block.
import 'dart:io'; // dart program to write to a file
void main(){
File re = File('book.txt');
try{
re.writeAsStringSync("Welcome to Dart File Write Handling");
}catch(e){
print("File not written");
}
}
We can use these try and catch error handling in dart for every files handling problem like copying, reading, deleting.
