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}");
})

copied to clipboard
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:$isSupportMultipleScreen");
copied to clipboard
1.4 (other Methods) Determine whether the current application has overlay window permissions #
bool checkOverlayPermission = await _iminViceScreenPlugin.checkOverlayPermission();
print("checkOverlayPermission:$checkOverlayPermission");
copied to clipboard
1.5 (other Methods) Apply for an overlay window permission to set the secondary screen as a persistent window #
await _iminViceScreenPlugin.requestOverlayPermission();
copied to clipboard
1.6 (other Methods) Open and close the secondary screen #
await _iminViceScreenPlugin.doubleScreenOpen(); /// open
await _iminViceScreenPlugin.doubleScreenClose(); /// close
copied to clipboard
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>
