Hello there 👋

I'm going to be using a shimmer in my application and thought this package was great! However, I desired more customization over the gradient.

Overview

I change GradientMask to supply the definition used for the underlying LinearGradient. The default values match the current gradient.

Text("Shimmering")
	.shimmering(gradientMask: .init(
		centerOpacity: 0.8,
		edgeOpacity: 0.3,
		startPoint: .topLeading,
		endPoint: .bottomTrailing,
		width: 0.1))

Since GradientMask.startPoint and GradientMask.endPoint are properties, this allows the gradient to "move" in different directions. Due to this, I think that this overrides #4.

Inverse mask

Currently, the gradient is applied as a plain .mask(...) which doesn't suite my needs, as it changes the opacity of the underlying view to the opacity of the edge points of the LinearGradient, and I don't think that a shimmer should change the opacity of the underlying view. GradientMask.inverse determines whether the mask should be inverted or not, therefore having the shimmer effect be the gradient itself, and not a mask over the gradient. I personally think this should be the default behavior but I won't change the current implementation.

Other

• I provide two view functions used to determine the mask
• Remove the defaults to the Shimmer object. Redundant for this package's use.
• Some personal linting styles applied
• Previews are updated to show GradientMask customization
• Update documentation. The phrases where the default was provided was redundant as they are already shown in the Xcode preview while you are reading them.

Shimme should animate from the leading to the trailing responding to the language direction. Also, the slash effect should be face forward. (aka forward slash)

Hi. If I have a view like this:

	@ViewBuilder var listView: some View {
		if isLoading {
			skeletonView.shimmer()
		} else {
			listView
		}
	}

Then even if isLoading is false is still consumes CPU. The more cells the more consumption. I have about 36% on my iPhone 11 even if there's no shimmering view on screen. If remove shimmering then CPU load is 0%.
