Overview #
This package is a practical Flutter (Dart) implementation of the Simple Widget Markup Language (SpWML).
SpWML allows for users to create statically flutter layout.
It also reduces the amount of program code required and often speeds up compilation.
Files output in SpWML have the extension .spwml.
Usage #
Quick Start #
Below is detailed documentation.
SpWML documentation
You can try how it works on the following sites.
SpWML Editor
The states of text fields, dropdowns, etc. are managed by the following manager classes,
so no special operations are required.
If you want to send user input values to the server, you can serialize the manager classes.

Sample code #
import 'package:flutter/material.dart';
import 'package:simple_widget_markup/simple_widget_markup.dart';

title: 'SpWML Example',
theme: ThemeData(
primarySwatch: Colors.green,
),
home: const SpWMLSample(title: 'SpWML Example'),
);
}
}

class SpWMLSample extends StatefulWidget {
const SpWMLSample({Key? key, required this.title}) : super(key: key);

final String title;

@override
State<SpWMLSample> createState() => _SpWMLSampleState();
}

class _SpWMLSampleState extends State<SpWMLSample> {

Widget _getSpWMLWidget(BuildContext context){
return SpWMLBuilder("(h1)Example text").build(context);
}

@override

Customize basic design #
Please rewrite _getSpWMLWidget in Sample code as follows.
Widget _getSpWMLWidget(BuildContext context) {
SpWMLFontStyle fontStyle1 = SpWMLFontStyle();
SpWMLFontStyle fontStyle2 = fontStyle1.deepCopy();
fontStyle2.styleMap[EnumSpWMLElementType.h1]!.fontWeight =
EnumFontWeight.light;
return Column(
children: [
SpWMLBuilder("(h1)Example text1", spWMLStyle: fontStyle1).build(context),
SpWMLBuilder("(h1)Example text2", spWMLStyle: fontStyle2).build(context),
],
);
}
copied to clipboard
The style can also be saved as a JSON file.
You can create a Map with toDict and restore it with fromDict.
Please consider if necessary.
SpWMLFontStyle test = SpWMLFontStyle.fromDict(fontStyle1.toDict());
