Here's a plain ol' boring QR Code: 28 | 29 | 30 | 31 | 44 | 47 | 48 |
32 | 33 | ```kotlin 34 | @Composable 35 | fun BoringPreview() { 36 | QrCodeView( 37 | data = "https://github.com/lightsparkdev/compose-qr-code", 38 | modifier = Modifier.size(300.dp) 39 | ) 40 | } 41 | ``` 42 | 43 | 45 | 46 |
49 | 50 | Meh... Let's spice it up a bit with a smiley face overlay: 51 | 52 | 53 | 54 | 73 | 76 | 77 |
55 | 56 | ```kotlin 57 | @Composable 58 | fun SmileyPreview() { 59 | QrCodeView( 60 | data = "https://github.com/lightsparkdev/compose-qr-code", 61 | modifier = Modifier.size(300.dp) 62 | ) { 63 | Smile( 64 | modifier = Modifier.fillMaxSize(), 65 | backgroundColor = Color.Yellow, 66 | smileColor = Color.Black 67 | ) 68 | } 69 | } 70 | ``` 71 | 72 | 74 | 75 |
78 | 79 | Cool, I guess we're getting somewhere. What about dark mode? Maybe we can also add some style with 80 | circular dots in the qr code... 81 | 82 | 83 | 84 | 115 | 118 | 119 |
85 | 86 | ```kotlin 87 | @Composable 88 | fun SmileyDarkPreview() { 89 | QrCodeView( 90 | data = "https://github.com/lightsparkdev/compose-qr-code", 91 | modifier = Modifier.size(300.dp), 92 | colors = QrCodeColors( 93 | background = Color.Black, 94 | foreground = Color.White 95 | ), 96 | dotShape = DotShape.Circle 97 | ) { 98 | Box( 99 | contentAlignment = Alignment.Center, 100 | modifier = Modifier 101 | .fillMaxSize() 102 | .clip(RoundedCornerShape(8.dp)) 103 | .background(Color.White) 104 | .padding(8.dp) 105 | .clip(RoundedCornerShape(8.dp)) 106 | .background(Color.Green) 107 | ) { 108 | Smile(modifier = Modifier.fillMaxSize(0.5f)) 109 | } 110 | } 111 | } 112 | ``` 113 | 114 | 116 | 117 |
120 | 121 | 122 | That's not bad! Let's add some even cooler styles, though. *cracks fingers*... 123 | 124 | 125 | 126 | 165 | 168 | 169 |
127 | 128 | ```kotlin 129 | @Composable 130 | fun PurpleAndGold() { 131 | val purple = Color(0xFF552583) 132 | val gold = Color(0xFFFDB927) 133 | QrCodeView( 134 | data = "https://github.com/lightsparkdev/compose-qr-code", 135 | modifier = Modifier.size(300.dp), 136 | colors = QrCodeColors( 137 | background = purple, 138 | foreground = gold 139 | ), 140 | dotShape = DotShape.Circle 141 | ) { 142 | Box( 143 | contentAlignment = Alignment.Center, 144 | modifier = Modifier 145 | .fillMaxSize() 146 | .clip(CircleShape) 147 | .background(purple) 148 | ) { 149 | BasicText( 150 | text = "L", 151 | style = TextStyle.Default.copy( 152 | color = gold, 153 | fontSize = 42.sp, 154 | fontWeight = FontWeight.ExtraBold, 155 | fontStyle = FontStyle.Italic, 156 | fontFamily = FontFamily.Serif 157 | ) 158 | ) 159 | } 160 | } 161 | } 162 | ``` 163 | 164 | 166 | 167 |
