字符串到双镖

代码示例

Flutter转string转int

// String -> int
main () {
    var one = int.parse('1');
    print(one == 1); // prints true
}

字符串到双镖

// String -> double
main () {
    var onePointOne = double.parse('1.1');
    print(onePointOne == 1.1); // prints true
}

dart中的字符串转int

import 'dart:convert';

void main() {
    var a = 10; // An integer
    var b = "20"; // A string
    var c = int.parse(b);
    print(a + c);
}

串int在镖

import 'dart:convert';

void main() {
    var a = 10; // An integer
    var b = "20"; // A string
    var c = int.parse(b);
    print(a + c);
}

convert string双颤动

var long2 = double.parse("STRING");

将字符串转换为双颤振

var long2 = double.parse("STRING");
