Description:

popup alert

This plugin allows you to show alert dialogs in your Flutter app from Java code.
Getting Started #
To use this plugin, add the following to your pubspec.yaml file:
dependencies:
flutter_alert_dialog: ^latest_version
copied to clipboard
Then, run flutter pub get.
Usage #
To show an alert dialog, call the showAlertDialog method from your Flutter code:
import 'package:flutter_alert_dialog/flutter_alert_dialog.dart';

void showAlertDialog() {
const channel = MethodChannel('flutter_alert_dialog');
channel.invokeMethod('showAlertDialog');
}
copied to clipboard
This will show an alert dialog with the title "My Alert Dialog" and the message "This is an alert dialog." The alert dialog will have two buttons: "OK" and "Cancel."
You can customize the title, message, and buttons of the alert dialog by passing a Map of options to the showAlertDialog method. For example, you could change the title to "My Custom Title" and the message to "This is a custom message" as follows:
void showAlertDialog() {
const channel = MethodChannel('flutter_alert_dialog');
channel.invokeMethod('showAlertDialog', {
'title': 'My Custom Title',
'message': 'This is a custom message',
});
}

You can also use the FlutterAlertDialogPlugin plugin to show other types of dialogs, such as a confirmation dialog or a list dialog. For more information, please refer to the plugin's documentation.
Example #
The following is an example of how to use the FlutterAlertDialogPlugin plugin to show an alert dialog:
import 'package:flutter/material.dart';
import 'package:flutter_alert_dialog/flutter_alert_dialog.dart';

void main() {
runApp(MyApp());
}

class MyApp extends StatelessWidget {
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text('Flutter AlertDialog Plugin Example'),
),
body: Center(
child: ElevatedButton(
onPressed: () {
showAlertDialog(context);
},
child: Text('Show Alert Dialog'),
),
),
),
);
}

void showAlertDialog(BuildContext context) {
const channel = MethodChannel('flutter_alert_dialog');
channel.invokeMethod('showAlertDialog', {
'title': 'My Custom Title',
'message': 'This is a custom message',
});
}
}
copied to clipboard
This example will show an alert dialog with the title "My Custom Title" and the message "This is a custom message." The alert dialog will have two buttons: "OK" and "Cancel."
Java Code #
The following is the Java code for the FlutterAlertDialogPlugin plugin:
package com.example.flutter_alert_dialog;

import android.app.Dialog;
import android.content.Context;
import androidx.appcompat.app.AlertDialog;
import android.content.DialogInterface;
import android.widget.Toast;

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;

/** FlutterAlertDialogPlugin */
public class FlutterAlertDialogPlugin implements FlutterPlugin, MethodCallHandler {
private MethodChannel channel;
private Context context;

@Override
public void onAttachedToEngine(@NonNull FlutterPluginBinding flutterPluginBinding) {
context = flutterPluginBinding.getApplicationContext();
channel = new MethodChannel(flutterPluginBinding.getBinaryMessenger(), "flutter_alert_dialog");
channel.setMethodCallHandler(this);
}

@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.equalsIgnoreCase("showAlertDialog")) {
String title = call.argument("title");
String message = call.argument("message");
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle(title);
builder.setMessage(message);
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// Handle the positive button click.
}
});
builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// Handle the negative button click.
}
});
AlertDialog dialog = builder.create();
dialog.show();
} else {
result.notImplemented();
}
}

@Override
public void onDetachedFromEngine(@NonNull FlutterPluginBinding binding) {
channel.setMethodCallHandler(null);
}
}
