Flutter-Plugin开发-(核心代码)

android端:

package com.example.ingeek_deviceInfo;

import androidx.annotation.NonNull;

import io.flutter.embedding.engine.plugins.FlutterPlugin;

import io.flutter.plugin.common.MethodCall;

import io.flutter.plugin.common.MethodChannel;

import io.flutter.plugin.common.MethodChannel.MethodCallHandler;

import io.flutter.plugin.common.MethodChannel.Result;

import io.flutter.plugin.common.PluginRegistry.Registrar;

/** IngeekDeviceInfoPlugin */

public class IngeekDeviceInfoPlugin implements FlutterPlugin, MethodCallHandler {

  /// The MethodChannel that will the communication between Flutter and native Android

  ///

  /// This local reference serves to register the plugin with the Flutter Engine and unregister it

  /// when the Flutter Engine is detached from the Activity

  private MethodChannel channel;

  private FlutterPluginBinding flutterPluginBinding;

  @Override

  public void onAttachedToEngine(@NonNull FlutterPluginBinding flutterPluginBinding) {

    channel = new MethodChannel(flutterPluginBinding.getBinaryMessenger(), "ingeek_deviceInfo");

    channel.setMethodCallHandler(this);

    this.flutterPluginBinding = flutterPluginBinding;

  }

  @Override

  public void onMethodCall(@NonNull MethodCall call, @NonNull Result result) {

    if (call.method.equals("getPlatformVersion")) {

      result.success("Android " + android.os.Build.VERSION.RELEASE);

    } else if (call.method.equals("getDeviceId")){

    result.success("getDeviceId");

    }

  }

  @Override

  public void onDetachedFromEngine(@NonNull FlutterPluginBinding binding) {

    channel.setMethodCallHandler(null);

  }

}

IOS端：

import Flutter

import UIKit

public class SwiftIngeekDeviceInfoPlugin: NSObject, FlutterPlugin {

  public static func register(with registrar: FlutterPluginRegistrar) {

    let channel = FlutterMethodChannel(name: "ingeek_deviceInfo", binaryMessenger: registrar.messenger())

    let instance = SwiftIngeekDeviceInfoPlugin()

    registrar.addMethodCallDelegate(instance, channel: channel)

  }

  public func handle(_ call: FlutterMethodCall, result: @escaping FlutterResult) {

    if("getPlatformVersion" == call.method){

      result("iOS " + UIDevice.current.systemVersion)

    }else if ("getDeviceId" == call.method){

      result(UIDevice.current.identifierForVendor)

    }



  }

}

Flutter端：

import 'dart:async';

import 'package:flutter/services.dart';

class IngeekDeviceInfo {

  static const MethodChannel _channel =

      const MethodChannel('ingeek_deviceInfo');

  static Future<String> get platformVersion async {

    final String version = await _channel.invokeMethod('getPlatformVersion');

    return version;

  }

  static Future<String> get getDeviceId async {

    final String deviceId = await _channel.invokeMethod('getDeviceId');

    return deviceId;

  }

}
