flutter_dax #

This is a flutter component library based on dax Interpreter。

Usage example #

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

var codeSnap = '''
  var i = 1;
  fun build() {
    return Scaffold(
      appBar: AppBar(
        title: Text("title")
      ),
      body: Column(
        children: [
          Text("count : ${i}"),
          TextButton(
           child: Text("click"),
             onPressed: (){
               setState((){
                i = i+1;
               });
            }
          )
        ]
      )
    );
  } ''';

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

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Dax Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: DaxPage(args: {"code": codeSnap}),
    );
  }
}

You can also use url to load code from remote server

Daxpage(args: {"url": "https://example.com/code.dart"})

Basic Components && Class #

The component library is based on flutter2.5, and covers most commonly used components and configurations. The usage method is completely compatible with flutter.

It is a wrapper of http.get and http.post, and adds some additional fields to the request header: Authorization, version-number, build-number, platform. If the response header content-type is application/json, it will automatically convert the response value to a json object.

Api.get(String url, {params})
Api.post(String url, {params})
