Quick start

Step 1: Include plugin to your project

dependencies:
  flutter_process_text: <latest version>

Run pub get and get packages.

Step 2: Create a new activity

Add the below code to your AndroidManifest.xml in the android\app\src\main\ folder.

  <activity 
        android:name=".ProcessTextActivity" 
        android:label="Process_Text"
        android:theme="@android:style/Theme.NoDisplay">
          <intent-filter>
              <action android:name="android.intent.action.PROCESS_TEXT" />
              <data android:mimeType="text/plain"/>
              <category android:name="android.intent.category.DEFAULT" />
          </intent-filter>
  </activity>

Note: You may change the android:name from ProcessTextActivity to anything you want. also change the android:label from Process_Text to the process action text that you want to display.

Step 3: Create new activity class

Create a new Java/Kotlin file with the same name as android:name in step 2.

Copy the below code and paste in the newly created file.

package com.divyanshushekhar.flutter_process_text_example;

import com.divyanshushekhar.flutter_process_text.FlutterProcessTextPlugin;
import io.flutter.embedding.android.FlutterActivity;
import android.os.Bundle;

public class ProcessTextActivity extends FlutterActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        boolean issAppRunning = MainActivity.getIsAppRunning();
        FlutterProcessTextPlugin.listenProcessTextIntent(issAppRunning);
    }
}

Note: Don't forget to change the package name in the above code.

Step 4: Changes in MainActivity

Make the necessary changes in the MainActivity class.

package com.divyanshushekhar.flutter_process_text_example;

import io.flutter.embedding.android.FlutterActivity;

import android.app.ActivityManager;
import android.content.Context;
import android.os.Bundle;
import java.util.List;

public class MainActivity extends FlutterActivity {
   private static boolean isAppRunning;

   public static boolean getIsAppRunning() {
     return isAppRunning;
   }

   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
        isAppRunning = isAppRunning(this);
   }

    public static boolean isAppRunning(Context context) {
        final String packageName = context.getPackageName();
        final ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        final List<ActivityManager.RunningAppProcessInfo> processInfo = activityManager.getRunningAppProcesses();
        if (processInfo != null)
        {
            for (final ActivityManager.RunningAppProcessInfo info : processInfo) {
                if (info.processName.equals(packageName)) {
                    return true;
                }
            }
        }
        return false;
    }
}

Step 5: Connect to flutter

First thing you need to do is to call the initialize method from the FlutterProcessText class in the initState() {} of the page.

FlutterProcessText.initialize();

OR

FlutterProcessText.initialize(
    showConfirmationToast: true,
    showRefreshToast: true,
    showErrorToast: true,
    confirmationMessage: "Text Added",
    refreshMessage: "Got all Text",
    errorMessage: "Some Error",
);

Step 6: Working with stream

There are two ways to work with stream, either create a StreamSubscription to listen for the incoming data or store the Stream and use it in StreamBuilder.

  late final StreamSubscription _processText;
  String text? = '';

  @override
  void initState() {
    super.initState();
    FlutterProcessText.initialize(
      showToast: true,
      confirmationMessage: "Text Added",
      refreshMessage: "Got all Text",
      errorMessage: "Some Error",
    );

    _processText = FlutterProcessText.getProcessTextStream.listen((event) {
      setState(() {
        text = event;
      });
    });
  }

  @override
  void dispose() {
    super.dispose();
    _processText.cancel();
  }

OR

late final Stream<String> _processText;
_processText = FlutterProcessText.getProcessTextStream;

Now use the stream in the StreamBuilder.

StreamBuilder<String?>(
  stream: _processText,
  builder: (context, snapshot) {
    return Text('Fetched Data: ${snapshot.data}');
  },
),

Get pending data

Get the pending data by calling the refreshProcessText method in FlutterProcessText class.

String? text = await FlutterProcessText.refreshProcessText;
