Clicking no will secure the app'), 111 | actions: [ 112 | CupertinoDialogAction( 113 | isDefaultAction: true, 114 | child: Text('No'), 115 | onPressed: () { 116 | Navigator.of(context).pop(false); 117 | }, 118 | ), 119 | CupertinoDialogAction( 120 | child: Text('Yes'), 121 | onPressed: () { 122 | Navigator.of(context).pop(true); 123 | }, 124 | ), 125 | ], 126 | ); 127 | }, 128 | ); 129 | } 130 | } 131 | } 132 | ``` 133 | 134 | Notice 3 importants part here: 135 | * Secure application is in MaterialApp/Builder so just above your app naviagator 136 | * I wrap the route i want to protect in onGenerateRoute with a **SecureGate** but you could put it anywhare you want if you only want to protect part of your page 137 | * Ask validation will display a dialog above everything to ask is you want to unlock app or not 138 | 139 | ### react to failed auth 140 | ```dart 141 | class SecureReacting extends StatefulWidget { 142 | @override 143 | _SecureReactingState createState() => _SecureReactingState(); 144 | } 145 | 146 | class _SecureReactingState extends State { 147 | bool locked = false; 148 | StreamSubscription _authEventsSub; 149 | @override 150 | void initState() { 151 | super.initState(); 152 | var lockController = SecureApplicationProvider.of(context, listen: false); 153 | _authEventsSub = lockController.authenticationEvents 154 | .where((s) => s == SecureApplicationAuthenticationStatus.FAILED) 155 | .listen((_) => lock()); 156 | } 157 | 158 | void lock() { 159 | if (mounted) { 160 | setState(() => locked = true); 161 | Navigator.of(context).pop(); 162 | } 163 | } 164 | 165 | @override 166 | void dispose() { 167 | _authEventsSub?.cancel(); 168 | super.dispose(); 169 | } 170 | 171 | @override 172 | Widget build(BuildContext context) { 173 | return locked ? Container() : Container(); 174 | } 175 | } 176 | ``` 177 | 178 | Notice 2 importants part here: 179 | * You are subscribing to a stream so don't forget to unsubscribe in onDispose 180 | * Since your animation from pop can take some time you might want also to have a locked variable here to display different content during transition 181 | 182 | 183 | 184 | ## API Docs 185 | [API Reference](https://pub.dev/documentation/secure_application/latest/) 186 | 187 | ## Basic understanding 188 | 189 | The library is mainly controller via the [SecureApplicationController](https://pub.dev/documentation/secure_application/latest/secure_application_controller/SecureApplicationController-class.html) which can be 190 | 191 | ### secured 192 | if the user switch app or leave app the content will not be visible in the app switcher 193 | and when it goes back to the app it will **lock** it 194 | 195 | ### locked 196 | the child of the **SecureGate**s will be hidden bellow the blurry barrier 197 | 198 | ### paused 199 | even if secured **SecureGate**s will not activate when user comes back to the app 200 | 201 | ### authenticated 202 | last authentication status. To help you manage visibility of some elements of your UI 203 | depending on auth status 204 | 205 | * **secureApplicationController.authFailed()** will set it to **false** 206 | * **secureApplicationController.authLogout()** will set it to **false** 207 | * **secureApplicationController.authSuccess()** will set it to **true** 208 | 209 | You could use the authenticationEvents for the same purpose as it is a BehaviorSubject stream 210 | 211 | ### Streams 212 | There is two different BehaviorStream (emit last value when you subscribe): 213 | 214 | * **authenticationEvents**: When there is a successful or unsucessful authentification (you can use it for example to clean your app if authentification is not successful) 215 | * **lockEvents**: Will be called when the application lock or unlock. Usefull for example to pause media when the app lock 216 | 217 | ## Example 218 | 219 | Look at example app to see a use case 220 | 221 | ## Authentication 222 | 223 | This tool does not impose a way to authenticate the user to give them back access to their content 224 | 225 | You are free to use your own Widget/Workflow to allow user to see their content once locked (cf **SecureApplication** widget argument [onNeedUnlock](https://pub.dev/documentation/secure_application/latest/secure_application/SecureApplication/onNeedUnlock.html)) 226 | 227 | Therefore you can use any method you like: 228 | * Your own Widget for code Authentication 229 | * biometrics with the [local_auth](https://pub.dev/packages/local_auth) package 230 | * ... 231 | 232 | ## Android 233 | On Android as soon as you **secure** the application the user will not be able to capture the screen in the app (even if unlocked) 234 | We might give an option to allow screenshot as an option if need arise 235 | 236 | ## iOS 237 | Contrary to Android we create a native frosted view over your app content so that content is not visible in the app switcher. 238 | When the user gets back to the app we wait for ~500ms to remove this view to allow time for the app to woke and flutter gate to draw 239 | 240 | # Widgets 241 | 242 | ## SecureApplication 243 | [Api Doc](https://pub.dev/documentation/secure_application/latest/secure_application/SecureApplication-class.html) 244 | this widget is **required** and need to be a parent of any Gate 245 | it provides to its descendant a SecureApplicationProvider that allow you to secure or open the application 246 | 247 | You can pass you own initialized SecureApplicationController if you want to set default values 248 | 249 | ## SecureGate 250 | [Api Doc](https://pub.dev/documentation/secure_application/latest/secure_gate/SecureGate-class.html) 251 | The **child** of this widget will be below a blurry barrier (control the amount of **blurr** and **opacity** with its arguments) 252 | if the provided SecureApplicationController is **locked** 253 | 254 | # Native workings 255 | 256 | ## Android 257 | When **locked** we set the secure flag to true 258 | ```kotlin 259 | activity?.window?.addFlags(LayoutParams.FLAG_SECURE) 260 | ``` 261 | When **opened** we remove the secure flag 262 | ```kotlin 263 | activity?.window?.clearFlags(LayoutParams.FLAG_SECURE) 264 | ``` 265 | 266 | ## iOS 267 | When app will become inactive we add a top view with a blurr filter 268 | We remove this app 500ms after the app become active to avoid your content form being breifly visible 269 | 270 | # Because we all want to see code in a Readme 271 | ```dart 272 | Widget build(BuildContext context) { 273 | var width = MediaQuery.of(context).size.width * 0.8; 274 | return MaterialApp( 275 | home: SecureApplication( 276 | onNeedUnlock: (secure) async { 277 | print( 278 | 'need unlock maybe use biometric to confirm and then sercure.unlock() or you can use the lockedBuilder'); 279 | // var authResult = authMyUser(); 280 | // if (authResul) { 281 | // secure.unlock(); 282 | // return SecureApplicationAuthenticationStatus.SUCCESS; 283 | //} 284 | // else { 285 | // return SecureApplicationAuthenticationStatus.FAILED; 286 | //} 287 | return null; 288 | }, 289 | onAuthenticationFailed: () async { 290 | // clean you data 291 | setState(() { 292 | failedAuth = true; 293 | }); 294 | print('auth failed'); 295 | }, 296 | onAuthenticationSucceed: () async { 297 | // clean you data 298 | 299 | setState(() { 300 | failedAuth = false; 301 | }); 302 | print('auth success'); 303 | }, 304 | child: SecureGate( 305 | blurr: blurr, 306 | opacity: opacity, 307 | lockedBuilder: (context, secureNotifier) => Center( 308 | child: Column( 309 | mainAxisAlignment: MainAxisAlignment.center, 310 | children: [ 311 | RaisedButton( 312 | child: Text('UNLOCK'), 313 | onPressed: () => secureNotifier.authSuccess(unlock: true), 314 | ), 315 | RaisedButton( 316 | child: Text('FAIL AUTHENTICATION'), 317 | onPressed: () => secureNotifier.authFailed(unlock: true), 318 | ), 319 | ], 320 | )), 321 | child: Scaffold( 322 | appBar: AppBar( 323 | title: const Text('Secure Window Example'), 324 | ), 325 | body: Center( 326 | child: Builder(builder: (context) { 327 | var valueNotifier = SecureApplicationProvider.of(context); 328 | return ListView( 329 | children: [ 330 | Text('This is secure content'), 331 | RaisedButton( 332 | onPressed: () => valueNotifier.secure(), 333 | child: Text('secure'), 334 | ), 335 | RaisedButton( 336 | onPressed: () => valueNotifier.open(), 337 | child: Text('open'), 338 | ), 339 | if (failedAuth == null) 340 | Text( 341 | 'Lock the app then switch to another app and come back'), 342 | if (failedAuth != null) 343 | failedAuth 344 | ?
