Tarsier

Secure chat application, powered by DIM-Flutter.

Getting started

0. Download source codes and requirements

cd ~/Documents/
mkdir github.com; cd github.com/

# requirements
mkdir dimchat; cd dimchat/
git clone https://github.com/dimchat/demo-flutter.git
cd ..

# project source codes
mkdir dimpart; cd dimpart/
git clone https://github.com/dimpart/tarsier.git

1. Test Android

Just open tarsier project by Android Studio and run it in a simulator.

2. Test iOS

After android peoject run, the Android Studio will also generate Podfile for iOS too.

2.1. Edit dimpart/tarsier/ios/Podfile, add permissions setting:

platform :ios, '12.0'

...

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
    
    target.build_configurations.each do |config|
      config.build_settings['GCC_PREPROCESSOR_DEFINITIONS'] ||= [
      '$(inherited)',
      # dart: PermissionGroup.camera
      'PERMISSION_CAMERA=1',
      # dart: PermissionGroup. photos
      'PERMISSION_PHOTOS=1',
      'PERMISSION_PHOTOS_ADD_ONLY=1',
      # dart: PermissionGroup.microphone
      'PERMISSION_MICROPHONE=1',
      ]
    end 
    
  end
end

then try to build iOS in Android Studio (click menu Build -> Flutter -> Build iOS), this step will install pods and initialize project configs;

2.2. Open dimpart/tarsier/ios/Runner.xcworkspace by Xcode

A) Set your team in TARGETS -> Runner -> Signing & Capabilities;

B) If error occurred while launching:

dyld[48747]: Library not loaded: @rpath/libswiftCore.dylib
  Referenced from: <XXXX-YYYY> /Users/..../Runner.app/Runner
  Reason: tried: '/Users/..../libswiftCore.dylib' (no such file),
    '/Applications/..../libswiftCore.dylib' (no such file),
    ...

click TARGETS -> Runner -> Build Settings in Xcode, search "rpath", check Runpath Search Paths, make sure "/usr/lib/swift" exists:

				LD_RUNPATH_SEARCH_PATHS = (
					"$(inherited)",
					/usr/lib/swift,
					"@executable_path/Frameworks",
				);

C) If error occurred with C++, search "Linker", check Other Linker Flags, make sure the flag "-lc++" exists:

				OTHER_LDFLAGS = (
					"$(inherited)",
					"-ObjC",
					"-lc++",
					"-l\"DIMClient\"",
					"-l\"DIMCore\"",
					"-l\"DIMPlugins\"",
					"-l\"DIMSDK\"",
					"-l\"DaoKeDao\"",
					"-l\"FMDB\"",
					"-l\"FiniteStateMachine\"",
					"-l\"Mantle\"",
					"-l\"MingKeMing\"",
					"-l\"ObjectKey\"",
					"-l\"OrderedSet\"",
					"-l\"SDWebImage\"",
					"-l\"SDWebImageWebPCoder\"",
					"-l\"StarTrek\"",
					"-l\"device_info_plus\"",
					"-l\"dim_flutter\"",
					"-l\"flutter_image_compress\"",
					"-l\"flutter_inappwebview\"",
					"-l\"image_picker_ios\"",
					"-l\"libwebp\"",
					"-l\"package_info_plus\"",
					"-l\"permission_handler_apple\"",
					"-l\"sqflite\"",
					"-l\"sqlite3\"",
					"-framework",
					"\"Foundation\"",
					"-framework",
					"\"ImageIO\"",
					"-framework",
					"\"Security\"",
				);

If nothing unexpected happens, your iOS app should be able to run now!

3. Test Windows

3.1. Edit dimchat/demo-flutter/dim_flutter/pubspec.yaml

dependencies:

  ...

  sqflite: ^2.2.6
  sqflite_common_ffi: ^2.3.3
#  sqflite_common_ffi_web: ^0.4.2

  fvp: ^0.16.1
  video_player: ^2.8.3
  chewie: ^1.8.1
  castscreen: ^1.0.2

3.2. Edit dimchat/demo-flutter/dim_flutter/lib/src/common/platform.dart

import 'dart:io' show Platform;

import 'package:flutter/foundation.dart';
import 'package:sqflite_common_ffi/sqflite_ffi.dart';
// import 'package:sqflite_common_ffi_web/sqflite_ffi_web.dart';
import 'package:fvp/fvp.dart';

import 'package:lnc/log.dart';

class DevicePlatform {

  ...

  /// patch for SQLite
  static void patchSQLite() {
    if (_sqlitePatched) {
      return;
    }
    if (isWeb) {
      // TODO: open for Web
      // // Change default factory on the web
      // databaseFactory = databaseFactoryFfiWeb;
    } else if (isWindows || isLinux) {
      // Initialize FFI
      sqfliteFfiInit();
      // Change the default factory
      databaseFactory = databaseFactoryFfi;
    }
    _sqlitePatched = true;
  }
  static bool _sqlitePatched = false;

  /// patch for Video Player
  static void patchVideoPlayer() {
    if (_videoPlayerPatched) {
      return;
    }
    if (isAndroid || isIOS || isMacOS || isWeb) {
      // Video Player support:
      // - Android SDK 16+
      // - iOS 12.0+
      // - macOS 10.14+
      // - Web Any*
    } else {
      // - Windows
      // - Linux
      // ...
      Log.info('register video player for Windows, Linux, ...');
      registerWith();
    }
    _videoPlayerPatched = true;
  }
  static bool _videoPlayerPatched = false;

}

If nothing unexpected happens, your desktop app should be able to run now!
