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;
