# Customization Theme

The class responsible for defining the theme is called `CheckoutTheme`.

**Customization Theme Class Structure:**

```swift
class CheckoutTheme(
    val uiMode: UiMode = UiMode.AUTO,
    val appearanceLight: Appearance ? = null,
    val appearanceDark : Appearance ? = null,
    val showPaymentDetails : Boolean = true,
)
```

#### [uiMode](#uimode)

Specifies the device theme mode, which can be set to:

* Light
* Dark
* Auto (automatically adjusts based on system settings)

#### [**appearanceLight & appearanceDark**](#appearancelight-and-appearancedark)

These are optional instances of the `Appearance` class, which enable UI customization for light mode and dark mode, respectively.

The `Appearance` class serves as the core inner class of `CheckoutTheme`, containing objects that define various UI components.

The component names within `Appearance` largely correspond to those described [here](#properties-description).

#### [**showPaymentDetails**](#showpaymentdetails)

A boolean field that determines whether the "Payment Details" section should be displayed or hidden.

## [Properties Description](#properties-description) <a href="#properties-description" id="properties-description"></a>

All properties are optional and can be customized by the user.

If a property is not specified, the default value (as defined in the Figma design [here](https://www.figma.com/proto/BmLOTN8QCvMaaIteZflzgG?content-scaling=fixed\&kind=proto\&node-id=1-624\&scaling=scale-down)) will be automatically applied.

## [Example](#example.1) <a href="#example.1" id="example.1"></a>

To build the `theme`, the user must follow steps similar to those outlined in the **test app file**.

**Code Snippet:**

```swift
val appearanceLight = CheckoutTheme.Appearance(
    mainTitleText = CheckoutTheme.Text(
        textColor = CheckoutTheme.Color(Color.WHITE),
        R.font.roboto_bold
    ),
    titleText = CheckoutTheme.Text(textColor = CheckoutTheme.Color(Color.BLACK)),
    subtitleText = CheckoutTheme.Text(textColor = CheckoutTheme.Color(Color.BLACK)),

    button = CheckoutTheme.Button(
        rippleColor = CheckoutTheme.RippleColor(
            color = Color.WHITE,
            rippleColor = Color.BLACK,
            colorDisabled = Color.GRAY
        ),
        textColor = CheckoutTheme.Color(color = Color.BLACK),
        fontType = R.font.roboto_bold
    ),

    margins = Margins(left = 12, top = 4, right = 12, bottom = 4),

    sdkBackgroundColor = CheckoutTheme.Color(color = Color.WHITE)
)

return CheckoutTheme(
    uiMode = CheckoutTheme.UiMode.AUTO,
    showPaymentDetails = showPaymentDetails,
    appearanceLight = appearanceLight,
    appearanceDark = appearanceDark,
)
```
