dependencies:
  template_parser: ^0.0.2

示例

以下是一个简单的使用示例：

import 'package:template_parser/template_parser.dart';

void main() {
  // 定义模板字符串
  final template = 'My name is {{FullName}}. I am {{ Age }}, have worked as a '
     '{{designation}} for a bigger company, in an agile team, working mostly '
     'on {{Skills}} platform.';

  // 创建一个模板模型列表
  final List<TemplateModel> models = [
    TemplateModel(variable: 'FullName', value: 'Sodipto Saha'),
    TemplateModel(variable: 'Age', value: '26'),
    TemplateModel(variable: 'designation', value: 'Senior Software Engineer'),
    TemplateModel(variable: 'Skills', value: 'Flutter,C# And .NET Core'),
  ];
  
  // 解析模板
  final parseTemplate = TemplateParser.parse(template, models);
  print(parseTemplate);
}

TemplateModel

TemplateModel用于定义模板变量及其对应的值。以下是其结构：

下面是完整的示例代码，展示了如何在Flutter应用中使用template_parser插件：

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

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Template Parser',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      debugShowCheckedModeBanner: false,
      home: TemplateParserPage(),
    );
  }
}

class TemplateParserPage extends StatelessWidget {
  TemplateParserPage({Key? key}) : super(key: key);

  final template = 'My name is {{FullName}}. I am {{ Age }}, have worked as a '
      '{{designation}} for a bigger company, in an agile team, working mostly '
      'on {{Skills}} platform.';

  final List<TemplateModel> models = [
    TemplateModel(variable: 'FullName', value: 'Sodipto Saha'),
    TemplateModel(variable: 'Age', value: '26'),
    TemplateModel(variable: 'designation', value: 'Senior Software Engineer'),
    TemplateModel(variable: 'Skills', value: 'Flutter,C# And .NET Core'),
  ];

  [@override](/user/override)
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: const Text('Template Parser'),
      ),
      body: Padding(
          padding: const EdgeInsets.symmetric(horizontal: 20),
          child: Column(

              ),
