Getting Started

Installation

flutter pub add imin_vice_screen

or Make a reference in the “pubspec.yaml” file

  dependencies:
    imin_vice_screen: ^0.0.1

Just see the example folder!

How to use:

Use flutter to draw the main and secondary screens, and use the encapsulation capability to communicate the main and secondary screens:

1. Distinguish the main screen from the secondary screen at the main entrance:

void main() {
  var defaultRouteName = window.defaultRouteName;
  if ("viceMain" == defaultRouteName) {
    viceScreenMain(); 
  } else {
    defaultMain();
  }
}

//主屏ui
void defaultMain() {
  runApp(MainApp());
}

//副屏ui
void viceScreenMain() {
  runApp(SubApp());
}

2. Use the encapsulation capability to communicate the main and secondary screens:

1.1 mainScreen to subScreen

  import 'package:imin_vice_screen/imin_vice_screen.dart';
  final _iminViceScreenPlugin = IminViceScreen();
 /// 1. send Message
  _iminViceScreenPlugin.sendMsgToViceScreen("data", params: {"params": "123"});
 /// 2. receive subScreen Message
 _iminViceScreenPlugin.mainStream.listen((event) {
    print("mainScreen receive data:${event}");
 })

1.2 subScreen to mainScreen

  import 'package:imin_vice_screen/imin_vice_screen.dart';
  final _iminViceScreenPlugin = IminViceScreen();
 /// 1. send Message
  _iminViceScreenPlugin.sendMsgToMainScreen("data", params: {"params": "456"});
 /// 2. receive mainScreen Message
  _iminViceScreenPlugin.viceStream.listen((event) {
    print("mainScreen receive data:${event}");
 })

1.3 (other Methods) Obtain whether the current device environment supports dual screens

   bool isSupportMultipleScreen = await _iminViceScreenPlugin.isMultipleScreen();
    print("isSupportMultipleScreen:$isSupportMultipleScreen");

1.4 (other Methods) Determine whether the current application has overlay window permissions

   bool checkOverlayPermission = await _iminViceScreenPlugin.checkOverlayPermission();
    print("checkOverlayPermission:$checkOverlayPermission");

1.5 (other Methods) Apply for an overlay window permission to set the secondary screen as a persistent window

   await _iminViceScreenPlugin.requestOverlayPermission();

1.6 (other Methods) Open and close the secondary screen

   await _iminViceScreenPlugin.doubleScreenOpen(); /// open
   await _iminViceScreenPlugin.doubleScreenClose(); /// close

3. After the initialization is complete, the secondary screen is displayed

android -> values -> attrs.xml Add configuration

   <!-- 是否在初始化时自动显示副屏 -->
  <bool name="autoShowSubScreenWhenInit">true</bool> 

4. LCD Vice screen display

1. LCD INIT

-- sendLCDCommand

import 'package:imin_vice_screen/enums.dart';
import 'package:imin_vice_screen/imin_vice_screen.dart';
  final iminViceScreenPlugin = IminViceScreen();
  await iminViceScreenPlugin.sendLCDCommand(LCDCommand.initLCD); // init  LCD
  await iminViceScreenPlugin.sendLCDCommand(LCDCommand.wakeLCD); // wake  LCD
  await iminViceScreenPlugin.sendLCDCommand(LCDCommand.sleepLCD); // sleep  LCD
  await iminViceScreenPlugin.sendLCDCommand(LCDCommand.cleanScreenLCD); // clean Screen

2. Send a string for display on the secondary screen

-- sendLCDString

import 'package:imin_vice_screen/imin_vice_screen.dart';
  final iminViceScreenPlugin = IminViceScreen();
  await iminViceScreenPlugin.sendLCDString('hello world');

3. Send a string for display on the secondary screen

-- sendLCDString
-- parameter: --- String content

import 'package:imin_vice_screen/imin_vice_screen.dart';
  final iminViceScreenPlugin = IminViceScreen();
  await iminViceScreenPlugin.sendLCDString('hello world');

4. Sends a multi-line subscreen content string

-- sendLCDMultiString
-- parameter: -- String[] contents -- int[] aligns

import 'package:imin_vice_screen/imin_vice_screen.dart';
  final iminViceScreenPlugin = IminViceScreen();
  await iminViceScreenPlugin.sendLCDMultiString(contents: ["سعيد بلقائك", "Des", "Hi"], aligns: [0, 1, 2]);

4. Sends a two-line subscreen content string

-- sendLCDDoubleString
-- parameter: -- String topText -- String bottomText

import 'package:imin_vice_screen/imin_vice_screen.dart';
  final iminViceScreenPlugin = IminViceScreen();
  await iminViceScreenPlugin.sendLCDDoubleString(
                    topText: 'Top  Cotent', bottomText: 'Bottom  Cotent');

4. Send pictures to display on the secondary screen

-- sendLCDBitmap
-- parameter: -- dynamic byte -> img URL Or Byte

import 'package:imin_vice_screen/imin_vice_screen.dart';
  final iminViceScreenPlugin = IminViceScreen();
  // use Byte
    Uint8List byte = await readFileBytes('assets/images/logo.png');
     await iminViceScreenPlugin.sendLCDBitmap(byte);
  
  // or use URL
  await iminViceScreenPlugin.sendLCDBitmap(
            'https://oss-sg.imin.sg/web/iMinPartner2/images/logo.png',
            pictureStyle: IminPictureStyle(
              width: 240,
              height: 320,
            ));
