Hi, I just started writing kotlin. I have this function:

private fun Toolbar() {
    TopAppBar(
        title = { Text(text = "About Device") }
    )
}

This is my import for Text

import androidx.compose.material3.Text

The Text is underlined red and I have this error

Overload resolution ambiguity. All these functions match.

public fun Text(text: String, modifier: Modifier = ..., color: Color = ..., fontSize: TextUnit = ..., fontStyle: FontStyle? = ..., fontWeight: FontWeight? = ..., fontFamily: FontFamily? = ..., letterSpacing: TextUnit = ..., textDecoration: TextDecoration? = ..., textAlign: TextAlign? = ..., lineHeight: TextUnit = ..., overflow: TextOverflow = ..., softWrap: Boolean = ..., maxLines: Int = ..., minLines: Int = ..., onTextLayout: ((TextLayoutResult) → Unit)? = ..., style: TextStyle = ...): Unit defined in androidx. compose. material3

any help with it ? Thanks

You may be better off asking in #C0B8M7BUY, it looks like it's a matter of how to use the Android Text class.

The error is telling you that there are two `fun Text`s which can take just a String ( your Text(text = "About Device")). The difference between them seems to be that one takes a parameter onTextLayout which has type ((TextLayoutResult) → Unit)? (a function, but can be null), defaulted to something, and one takes a parameter onTextLayout which has type (TextLayoutResult) → Unit (a function, but cannot be null) which is also defaulted.

You can probably resolve it by passing a value as onTextLayout, either null or {_ -> }, but it seems an odd API design for Android.

(I wonder if your compile classpath is a bit mucked up? It seems wrong that you've got both those functions on the compile classpath at the same time...)

[ephemient]

there are only two Text overloads defined by material3, and they are not ambiguous (String/AnnotatedString parameter)

[ephemient]

however, one of the conflicting overloads there appears to be from material (material design 2)

[ephemient]

you should not import both, or at least you should alias one while importing, to avoid confusion like this

@ephemient I deleted the material3 implementation that was not in use and everything works fine. Thank you.

@Rob Elliot thank you as well
