flutter check if string starts with RegExp

Question

in flutter if we want to check if a string starts with a specific character...we can achieve that by:

var string = 'Dart';
string.startsWith('D');  // true

what if we want to check if the given string starts with multiple characters....i want to achieve this behaviour:

RegExp myRegExp = ('a-zA-Z0-9');
var string = 'Dart';
string.startsWith('D' + myRegExp);

is the above code is right?!!

my goal is to check if the string starts with a letter i specify...then a RegExp.... not to check if the string starts with 'D' only and thats it...

Answer 1

I think you'll want something like string.startsWith(RegExp('D' + '[a-zA-Z0-9]'));
