@Composable
fun gradientDemo() {
val orange = Color(0xFFFFFFA500)
Box(modifier = Modifier.drawWithCache {
val gradient = LinearGradient(
0.0f to Color.Red,
0.2f to Color.Red,
0.2f to orange,
0.4f to orange,
0.4f to Color.Yellow,
0.6f to Color.Yellow,
0.6f to Color.Green,
0.8f to Color.Green,
0.8f to Color.Blue,
1.0f to Color.Blue,
startX = 0.0f,
endX = size.width,
startY = 0f,
endY = 0f
)
onDraw {
drawRect(brush = gradient)
}
})
}The gradient example shown can be written with the above sample code and the following import:
import androidx.compose.ui.graphics.LinearGradient❤️ 1
