weplenish / flutter_wifi_connect Goto Github PK

Hi,

First, thanks for creating this plugins with minimal dependencies and using the latest Android APIs.

I found some issues while trying to use this plugin with Flutter 1.22.5 and xcode 12.3. The Swift code does not compile in my environment. Here are some of the problems:

• platform version in podspec file is pointing to 8.0 instead of 11.0

   /flutter/.pub-cache/hosted/pub.dartlang.org/flutter_wifi_connect-0.0.4/ios/Classes/SwiftFlutterWifiConnectPlugin.swift:15:16: error: 'disconnect()' is only available in iOS 11 or newer
            result(disconnect())
                   ^
    /flutter/.pub-cache/hosted/pub.dartlang.org/flutter_wifi_connect-0.0.4/ios/Classes/SwiftFlutterWifiConnectPlugin.swift:15:16: note: add 'if #available' version check
            result(disconnect())

• missing argument labels

    /flutter/.pub-cache/hosted/pub.dartlang.org/flutter_wifi_connect-0.0.4/ios/Classes/SwiftFlutterWifiConnectPlugin.swift:23:33: error: missing argument label 'arguments:' in call
            let args = GetArgs(call.arguments)

• return type in connect cannot be Bool

/flutter/.pub-cache/hosted/pub.dartlang.org/flutter_wifi_connect-0.0.4/ios/Classes/SwiftFlutterWifiConnectPlugin.swift:77:42: error: cannot convert return expression of type 'Void' to return type 'Bool'
        NEHotspotConfigurationManager.shared.apply(hotspotConfig) { [weak self] (error) in

• unhandled exception from GetArgs

I'm submitting a PR for your review which addresses the above issues. I tested it on iOS 14.2 and it seems to be working fine.

Thank you!

FlutterWifiConnectPlugin.kt: (350, 51): Smart cast to 'ConnectivityManager.NetworkCallback' is impossible, because 'this.networkCallback' is a mutable property that could have been changed by this time

I implemented this package to my project, seems sometimes work sometimes not.

Especially when I used to connect on system setting, it won't work on my project mobile app.

flutter_wifi_connect-0.0.7/android/src/main/kotlin/com/weplenish/flutter_wifi_connect/FlutterWifiConnectPlugin.kt: (227, 14): Using 'maxBy((T) -> R): T?' is an error. Use maxByOrNull instead.

Hello Guys,

for now, this package will have new updates in:

https://pub.dev/packages/plugin_wifi_connect

me and "my team', are working together to continues this project, with permission of weplenish.

thank you and let's do it ;)

The plugin wifi_configuration uses a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if this plugin supports the Android V2 embedding.
Otherwise, consider removing it since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding:
https://flutter.dev/go/android-plugin-migration.

Many functions throw MissingPluginException, like FlutterWifiConnect.deactivateWifi() and such.

Greetings everyone, I am trying to use the flutter wifi connect plugin, after many attempts I have not been successful

I added the bad permissions without success, could someone help me with this problem?

Hi,

First, thanks for creating this plugins with minimal dependencies and using the latest Android APIs.

I'd like to propose some improvements for the Android pluging.

• on Android API < 29 support connection without requiring location permissions.

wifiManager.connectionInfo.ssid requires location permission, as an alternative the ssid could be obtained from info.getExtraInfo().

In the change receiver once could check both connectionInfo and extraInfo to cover both cases

          result.success(wifiManager.connectionInfo.ssid == wifiConfiguration.SSID || info.getExtraInfo() == wifiConfiguration.SSID)

• implement disconnect method on Android

Some application need to programatically disconnect from the peer to peer network and go back to the "default" WiFi/Internet connection. On API < 29 this could be done by calling wifiManager.disconnect(), not the nicest but it works. On API >=29, it is a bit more involved but cleaner: unregister the network callback, and unbind the process from the network.

Note: on API >= 29, the network callback was being removed on onAvailable which caused the connection to be disconnected as soon as it was connected.

• issue with wpa2/wpa3 on Android 11

On Android 11 (didn't test on Android 10) setWpa2Passphrase and setWpa3Passphrase are mutually exclusive. I propose to add an argument to explicitly ask for WPA3 when required by the application. The error is:

E/flutter (31808): [ERROR:flutter/lib/ui/ui_dart_state.cc(177)] Unhandled Exception: PlatformException(error, only one of setIsEnhancedOpen, setWpa2Passphrase,setWpa3Passphrase, setWpa2EnterpriseConfig or setWpa3EnterpriseConfig can be invoked for network specifier, null, java.lang.IllegalStateException: only one of setIsEnhancedOpen, setWpa2Passphrase,setWpa3Passphrase, setWpa2EnterpriseConfig or setWpa3EnterpriseConfig can be invoked for network specifier

I'm submitting a PR with the above proposed changes. Happy to discuss them. Tested on Android 8.1 (Nexus 5X) and Android 11 (Pixel 2(

Thank you!

Hello, I have a few question that I hoping someone can help me with.
flutter doctor

I am trying to use this library and I am not quite sure if I am using it effectively.

Questions:

1. Can you connect to a normal wifi?

I have tried to connect it to my home wifi and yielded this results:

FlutterWifiConnect.connectToSecureNetwork(ssid, password: WPA2)
It always connects (regardless if the password is correct or not) but always without internet connection.

FlutterWifiConnect.connect(ssid) (Having open my wifi):
It always connects but without internet connection.

2. If it is only for IOT devices, can you communicate with them via Sockets?

If I connect to a device that generates their own wifi (wifi is always without internet obviously) can I communicate with it using sockets?

I can manually connect to its wifi and talk to it using TCP sockets,
does the connection made by this plugin holds the same behaviour in order to automatize the wifi connection process?

Thank you very much in advance.
