Flutter Spelling Number

Flutter Spelling Number 是一个插件，可以将数字转换为单词（即阿拉伯语中的 “تفقيط” 或 “将数字转换为文字”）。

示例

将数字转换为单词

SpellingNumber(
  lang: "en",
  wholesUnit: "ton",
  fractionUnit: "kg",
  digitsLengthW2F: 3,
  decimalSeperator: "and"
).convert(100.951); // => One Hundred Ton And Nine Hundred Fifty-One Kg

将美元和美分转换为单词

SpellingNumber(
  lang: "en",
  wholesUnit: "dollar",
  fractionUnit: "cent",
  digitsLengthW2F: 2,
  decimalSeperator: "and"
).convert(123.45); // => One Hundred Twenty-Three Dollars And Forty-Five Cents

将重量转换为单词

SpellingNumber(
  lang: "en",
  wholesUnit: "Ton",
  fractionUnit: "Kg",
  digitsLengthW2F: 3,
  decimalSeperator: "and"
).convert(100.951); // => One Hundred Ton And Nine Hundred Fifty-One Kg

阿拉伯语数字转换为单词

SpellingNumber(
  lang: "ar",
  wholesUnit: "طن",
  fractionUnit: "كيلو غرام",
  digitsLengthW2F: 3,
  decimalSeperator: "و"
).convert(100.951); // => مائة طن وتسعمائة وواحد وخمسون كيلو غرام

特性

• 支持14种语言，包括阿拉伯语
• 可以指定整数单位、分数单位和小数分隔符
• 可以将货币和重量数字转换为单词

安装

使用Dart

$ dart pub add spelling_number

使用Flutter

$ flutter pub add spelling_number

这将在你的 pubspec.yaml 文件中添加一行：

dependencies:
  spelling_number: ^0.0.4

使用方法

导入

在你的Dart代码中，你可以这样使用：

import 'package:spelling_number/spelling_number.dart';

import 'dart:developer';

import 'package:flutter/material.dart';
import 'package:spelling_number/spelling_number.dart';
