In Flutter, you can use the try-catch statement to catch errors that might occur in your code.

For example:


try {
  // code that might throw an exception
} catch (e) {
  // handle the exception
}

You can also specify multiple catch blocks to handle different types of exceptions differently.

For example:

try {
  // code that might throw an exception
} on Exception1 {
  // handle Exception1
} on Exception2 {
  // handle Exception2
} catch (e) {
  // handle any other exceptions
}

Alternatively, you can use the try-on-syntax to specify the type of exception to catch.

For example:

try {
  // code that might throw an exception
} on Exception1 catch (e) {
  // handle Exception1
} on Exception2 catch (e) {
  // handle Exception2
} on Exception catch (e) {
  // handle any other exceptions
}
