In Dart, you can split a string into multiple substrings based on a specified separator or pattern.
Here's an example of how to split a string using a separator:
String str = "hello,world";
List parts = str.split(",");
print(parts); // output: ["hello", "world"]
In the example above, the split() method is used to split the string str into two separate strings using the separator ,.
If you want to split a string based on a regular expression pattern, you can use the split() method with the regular expression pattern inside:
String str = "hello@world.com";
List parts = str.split(RegExp(r"[@.]"));
print(parts); // output: ["hello", "world", "com"]
In this example, the split() method is used with a regular expression pattern that matches both @ and . characters. As a result, the string is split into three substrings: "hello", "world", and "com".
