Install FlutterLab

• macOS → Download from App Store

• Windows → FlutterLabSetup.exe (Download from github)

Usage

import 'package:flutter_lab/flutter_lab.dart';

Wrap MyApp() with FlutterLab widget, to connect FlutterLab App

void main() {

  WidgetsFlutterBinding.ensureInitialized();

  // ...

  runApp(
    const FlutterLab(
      child: MyApp(),
    ),
  );
}

Change Container widget to LabContainer (add Lab prefix) to manage parameters from FlutterLab App

LabContainer(
  // Container parameters
  width:300,
  height:200,
);

LabOpacity(
  opacity: 0.5,
  chid: Text("new"),
);

LabRow(
  children: [
    LabPadding(
      padding: EdgeInsets.all(8),
      child: Text("design"),
    ),
    Stack(
      children:[
        LabPositioned(
          child:Icon(Icons.add),
        ),
      ],
    ),
  ],
);

These widgets can be used

• Container -> LabContainer
• Padding -> LabPadding
• Row -> LabRow
• Column -> LabColumn
• Stack -> LabStack
• Align -> LabAlign
• Positioned -> LabPositioned
• SizedBox -> LabSizedBox
• Opacity -> LabOpacity
• Icon -> LabIcon

Detail

In order to control specific widgets, the "name" parameter can be used. "name" value and FlutterLab App widget name must be the same.

LabContainer(
  name: "background", // Rename the Container widget to "background" in FlutterLab App
  width: 300,
  height: 200,
  child: Row(
    children:[
      LabContainer(
        name: "box", // Rename the Container widget to "box" in FlutterLab App
        color: Colors.blue,
      ),
      LabContainer(
        name: "box",
        color: Colors.blue,
      ),
    ],
  ),
);

LabOpacity(
  name: "Opacity 2", 
  child: ...
);

LabPadding(
  name: "box padding",
  padding: EdgeInsets.all(8),
  child: ...
);

Connection

If needed, these parameters can be added to FlutterLab.

Hot restart is required after changing the parameters.

  runApp(
    const FlutterLab(
      url: "http://192.168.1.200", //default "http://localhost"
      port: 3010, //default 3000
      child: MyApp(),
    ),
  );

This package uses socket_io_client. If required, the connection solutions here can be used.
