How to Apply Stroke Effects to Text in Jetpack Compose
Exploring DrawStyle API for Text Stroke Effects in Jetpack Compose
Unless you’re a Multimillion or a Billion dollar company, you probably don’t have a multimillion-dollar ad budget or professional Spinners. Your product needs to stand out on its own merits like App Quality, Performance, UI design, and User Experience. Most companies don't care about you, your product, and your vision or dreams.

Conclusion
Let's get started.
We’ll use Stroke drawStyle, which provides information for drawing content with a stroke.
Let’s first look at what we have in Stroke API,
class Stroke(
val width: Float = 0.0f,
val miter: Float = DefaultMiter,
val cap: StrokeCap = DefaultCap,
val join: StrokeJoin = DefaultJoin,
val pathEffect: PathEffect? = null
) : DrawStyle() { }
width — Configure the width of the stroke in pixels
miter — Set the stroke miter value. This is used to control the behavior of miter joins when the joins angle is sharp. This value must be >= 0
cap — Return the paint’s Cap, controlling how the start and end of stroked lines and paths are treated. The default is StrokeCap.Butt
join — Set the treatment where lines and curve segments join on a stroked path. The default is StrokeJoin.Miter
pathEffect — Effect to apply to the stroke, null indicates a solid stroke line is to be drawn
