The next update of this package will add the support of recording videos, adding caption to captured/storage images, and much more features.

Usage

Permission Setup

You only have to add permissions in your project and the package will do the rest. The following permissions are required:

1. camera
2. microphone
3. local storage

Android

1. Add the following to your "gradle.properties" file:

android.useAndroidX=true
android.enableJetifier=true

2. In order to use the recording feature, make sure you set the compileSdkVersion in your "android/app/build.gradle" file to 21:

android {
  compileSdkVersion 21
  ...
}

3. Make sure you replace all the android. dependencies to their AndroidX counterparts (a full list can be found here: https://developer.android.com/jetpack/androidx/migrate).

Add permissions to your AndroidManifest.xml file.

 <uses-permission android:name="android.permission.INTERNET"/>
    <!-- Permissions options for the `storage` group -->
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <!-- Permissions options for the `camera` group -->
    <uses-permission android:name="android.permission.CAMERA"/>
    <!-- Permissions options for the `RECORD_AUDIO` group -->
    <uses-permission android:name="android.permission.RECORD_AUDIO" />

IOS

    <!-- Permission options for the `camera` group -->
    <key>NSCameraUsageDescription</key>
    <string>camera</string>
    <!-- Permission options for the `microphone` group -->
    <key>NSMicrophoneUsageDescription</key>
    <string>microphone</string>
    <!-- Permission options for the `photos` group -->
    <key>NSPhotoLibraryUsageDescription</key>
    <string>photos</string>

add this to your Podfile

  target.build_configurations.each do |config|
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
        '$(inherited)',

        'PERMISSION_CAMERA=1',
        'PERMISSION_MICROPHONE=1',
        'PERMISSION_PHOTOS=1',

      ]

    end

Calling

Simply call the ChatScreen
ChatMessages: the chat screen requires a list of chat messages, and to make it easy, the ChatMessage model contains a fromJson() method so you can iterate the list of stored ChatMessage from your back-end, and an example of a ChatMessage

ChatMessage(
      isSender: true,
      text: 'this is a banana',
      chatMedia: ChatMedia(
        url:
            'https://images.pexels.com/photos/7194915/pexels-photo-7194915.jpeg?auto=compress&cs=tinysrgb&h=750&w=1260',
        mediaType: MediaType.imageMediaType(),
      ),
    )

This package also provides you with a ChatMessage model when using these required methodsonTextSubmit, handleRecord , handleImageSelect and the full code will be like this:

 ChatScreen(
        scrollController: scrollController,
        messages: messages,
        onSlideToCancelRecord: () {
          log('not sent');
        },
        onTextSubmit: (textMessage) {
          setState(() {
            messages.add(textMessage);

            scrollController
                .jumpTo(scrollController.position.maxScrollExtent + 50);
          });
        },
        handleRecord: (audioMessage, canceled) {
          if (!canceled) {
            setState(() {
              messages.add(audioMessage!);
              scrollController
                  .jumpTo(scrollController.position.maxScrollExtent + 90);
            });
          }
        },
        handleImageSelect: (imageMessage) async {
          if (imageMessage != null) {
            setState(() {
              messages.add(
                imageMessage,
              );
              scrollController
                  .jumpTo(scrollController.position.maxScrollExtent + 300);
            });
          }
        },
      )
