I encountered an error while implementing the quick opening feature for assets in Dart language

IntelliJ Platform
1

When I held down the Ctrl key and clicked on the string, it opened the file correctly, but there was an AssertionError error in the console

this is my code，how can I fix it

internal class AssetPsiReference(
    element: DartStringLiteralExpressionImpl,
    val fileResult: DartStringIconShowInlay.FileResult
) :
    PsiReferenceBase<PsiElement?>(element, TextRange(1, element.string!!.length + 1)) {
    override fun resolve(): PsiElement? {
        return ApplicationManager.getApplication().runReadAction<PsiElement?> {
            val relativePath = fileResult.basePath
            val projectRoot = element.project.guessProjectDir() ?: return@runReadAction null
            val targetFile = projectRoot.findFileByRelativePath(relativePath) ?: return@runReadAction null
            PsiManager.getInstance(element.project).findFile(targetFile)
        }
    }
}

The code that throws this exception is the following:

assert !file.getFileType().isBinary();

Do you know how a binary file happened to appear in this call?
