Flutter String格式化

请看原文： http://tryenough.com/flutter-stringformat

在Android和iOS平台都有相应的方法进行字符串的格式化，但是在flutter中却没有直接提供
在flutter上可以借助一个插件来进行格式化：
sprintf
import ‘package:sprintf/sprintf.dart’;

例子
import ‘package:sprintf/sprintf.dart’;

void main() {
print(sprintf(“%04i”, [-42]));
print(sprintf(“%s %s”, [“Hello”, “World”]));
print(sprintf(“%#04x”, [10]));

double seconds = 5.0;
String name = ‘Dilki’;
List<String> pets = [‘Cats’, ‘Dogs’];

String sentence1 = sprintf(‘Sends %2.2f seconds ago.’, [seconds]);
String sentence2 = sprintf(‘Harry likes %s, I think %s likes %s.’, [pets[0], name, pets[1]]);

print(sentence1);
print(sentence2);

}
