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:
import 'package:sprintf/sprintf.dart';
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); }
