Stupid basic question but … is it possible anyhow to change cursor color of basic text field?

Yes, there’s a colors parameter that allows you to change several colors of the component

<https://developer.android.com/reference/kotlin/androidx/compose/material/TextFieldColors>

```BasicTextField(
        value = value,
        onValueChange = onChangeText,
        modifier = modifier.then(
            Modifier
                .fillMaxWidth()
                .background(
                    if (isFocused.value) Style.colors.inputActive else Style.colors.inputIdle
                )
                .onFocusChanged {
                    isFocused.value = it.isFocused
                }
        ),
        interactionSource = interactionSource,
        enabled = true,
        singleLine = singleLine,
        textStyle = textStyle,
    ) {
        TextFieldDefaults.TextFieldDecorationBox(
            value = value,
            innerTextField = it,
            singleLine = singleLine,
            visualTransformation = visualTransformation,
            interactionSource = interactionSource,
            leadingIcon = leadingIcon,
            enabled = true,
            trailingIcon = trailingIcon,
            colors = TextFieldDefaults.textFieldColors(
                containerColor = if (isFocused.value) Style.colors.inputActive else Style.colors.inputIdle,
                cursorColor = Style.colors.textLink,
                focusedIndicatorColor = Color.Transparent,
                unfocusedIndicatorColor = Color.Transparent,
            ),
            contentPadding = contentPaddingValues,
            placeholder = placeholder,
        )
    }
}```


have this and it just does not work :disappointed:

Oh I see - hmm that should in theory work on BasicTextField

This does not change cursor color at all so that is why i am completely confused

Yeah looking through the implementation it’s not immediately clear how the `cursorBrush` parameter on BasicTextField intersects with TextFieldColors on the inner decoration box. I assume you’ve tried changing cursorBrush on BasicTextField already?

Can you please check this demo code to see if what you are looking for is in there?

<https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/foundation/foundation/integration-tests/foundation-demos/src/main/java/androidx/compose/foundation/demos/text/TextFieldCursorBlinkingDemo.kt|https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/foundation/foundation/integration-tests/foundation-demos/src/main/java/androidx/compose/foundation/demos/text/TextFieldCursorBlinkingDemo.kt>

In BasicTextField it is a param named cursorBrush

<https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/material3/material3/src/commonMain/kotlin/androidx/compose/material3/TextField.kt;l=199?q=TextField.kt|https://cs.android.com/androidx/platform/frameworks/support/+/androidx-main:compose/material3/material3/src/commonMain/kotlin/androidx/compose/material3/TextField.kt;l=199?q=TextField.kt>

In general i think code search might help a lot, and might be easier to understand  than the documentation for engineers :)

Another e.g..: <https://youtu.be/_qls2CEAbxI?t=503|here> we’re using BasicTextField’s cursorBrush param with a gradient brush
