如何实现类似于:How to get a substring between two strings in PHP?但在DART中的解决方案
For example I have a String:
String data = "the quick brown fox jumps over the lazy dog"
I have two other Strings: quick and over
I want the data inside these two Strings and expecting result:
brown fox jumps
您可以使用String.indexOf和String.substring组合使用:
void main() {
const str = "the quick brown fox jumps over the lazy dog";
const start = "quick";
const end = "over";
final startIndex = str.indexOf(start);
final endIndex = str.indexOf(end, startIndex + start.length);
print(str.substring(startIndex + start.length, endIndex)); // brown fox jumps
}
另请注意，startIndex是inclusive，而endIndex是exclusive.
