This annotation automatically generates navigation code for you, reducing boilerplate and making your navigation logic cleaner and easier to maintain. 17 | 18 | Generated Helper Code Pattern: 19 | The generated navigation helper will be named as: YOUR_COMPOSABLE_FUNCTION_NAME + GraphNode. 20 | 21 | Example Usage: 22 | 23 | ``` 24 | @NavigationNode(route = "screen_with_optional_arguments", args = arrayOf("id", "name"), 25 | optionalArgs = arrayOf("age","nickName") 26 | ) 27 | @Composable 28 | fun ScreenWithOptionalArguments( 29 | id: String, 30 | name: String, 31 | nickName: String?, 32 | age: String? 33 | ) { 34 | Column(modifier = Modifier.fillMaxSize()) { 35 | Text(text = "OK, you're $name with id as $name, your nick name is ${nickName?:"Undefined"}, and your age is ${age?:"Undefined"}") 36 | } 37 | } 38 | ``` 39 | 40 | this gives you a generated code like this : 41 | 42 | ``` 43 | public object ScreenWithOptionalArgumentsGraphNode { 44 | public val rawRoute: String = "screen_with_optional_arguments" 45 | 46 | public val route: String = 47 | "screen_with_optional_arguments/{id}/{name}?age={age}&nickName={nickName}" 48 | 49 | private val args: Array = arrayOf("id", "name") 50 | 51 | private val optionalArgs: Array = arrayOf("age", "nickName") 52 | 53 | public const val age: String = "age" 54 | 55 | public const val nickName: String = "nickName" 56 | 57 | public const val id: String = "id" 58 | 59 | public const val name: String = "name" 60 | 61 | public fun navigationRoute( 62 | id: String, 63 | name: String, 64 | age: String?, 65 | nickName: String?, 66 | ): String { 67 | val ret = buildString { 68 | append(rawRoute) 69 | append("/$id") 70 | append("/$name") 71 | append("?") 72 | if (optionalage != null) { 73 | append("age=$age") 74 | append("&") 75 | } 76 | if (optionalnickName != null) { 77 | append("nickName=$nickName") 78 | } 79 | } 80 | return ret 81 | } 82 | } 83 | ``` 84 | 85 | if you don't declare args or optionalArgs for your annotation the code would be simpler and you won't see any related code for those parameters 86 | 87 | rawRoute = raw version of the route without declraing needed arguments 88 | 89 | route = processed version of route which you can pass to you NavHost 90 | 91 | navigationRoute = the fucntion which you can pass your argument and optionalArguments (if there're any) and in return it will pass you the route you need to pass to navController.navigate() function 92 | 93 | You can then navigate effortlessly with the generated helper functions: 94 | 95 | ``` 96 | navController.navigate(ScreenWithOptionalArgumentsGraphNode.navigationRoute( 97 | id = id, name = name, optionalnickName = "Sadegh", optionalage = null 98 | ) 99 | ``` 100 | Or use it within a composable block for handling back stack entries: 101 | 102 | ``` 103 | composable(ScreenWithOptionalArgumentsGraphNode.route) {backStackEntry -> 104 | val id = checkNotNull(backStackEntry.arguments?.getString(ScreenWithOptionalArgumentsGraphNode.id)) 105 | val name = checkNotNull(backStackEntry.arguments?.getString(ScreenWithOptionalArgumentsGraphNode.name)) 106 | val nickName = backStackEntry.arguments?.getString(ScreenWithOptionalArgumentsGraphNode.nickName) 107 | val age = backStackEntry.arguments?.getString(ScreenWithOptionalArgumentsGraphNode.age) 108 | ScreenWithOptionalArguments( 109 | name = name, 110 | id = id, 111 | nickName = nickName, 112 | age = age 113 | ) 114 | } 115 | ``` 116 |
