Hi All, Is there any way to display alert dialog on full width?

@Vinay Gaba Sir! any suggestions?

I am not sure if it is now possible. But i modified the dialog implementation to be able to decide in my own layout the size and transparency.

@Composable
fun FullScreenTransparentDialog(onCloseRequest: () -> Unit, children: @Composable () -> Unit) {
    val view = ViewAmbient.current

    val dialog = remember(view) { DialogWrapperTransparent(view, onCloseRequest) }
    dialog.onCloseRequest = onCloseRequest

    onActive {
        dialog.show()


        onDispose {
            dialog.dismiss()
            dialog.disposeComposition()
        }
    }

    val composition = compositionReference()
    onCommit {
        dialog.setContent(composition) {
            Box(Modifier.semantics {
                this.dialog()
            }) {
                children()
            }
        }
    }
}

private class DialogWrapperTransparent(composeView: View, var onCloseRequest: () -> Unit) : Dialog(composeView.context) {
    val frameLayout = FrameLayout(context)
    private var composition: Composition? = null
    init {
        window!!.apply {
            requestFeature(Window.FEATURE_NO_TITLE)

            setBackgroundDrawableResource(android.R.color.transparent)
            setFlags(0, WindowManager.LayoutParams.FLAG_DIM_BEHIND)
            addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)

            val displayRect = Rect()
            decorView.getWindowVisibleDisplayFrame(displayRect) // This call is necessary to get the full screen. I do not know why :-(
            setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT)
        }

        setContentView(frameLayout)
        ViewTreeLifecycleOwner.set(frameLayout, ViewTreeLifecycleOwner.get(composeView))
        ViewTreeViewModelStoreOwner.set(frameLayout, ViewTreeViewModelStoreOwner.get(composeView))
        ViewTreeSavedStateRegistryOwner.set(
                frameLayout,
                ViewTreeSavedStateRegistryOwner.get(composeView)
        )
    }

    fun setContent(parentComposition: CompositionReference, children: @Composable () -> Unit) {
        // TODO: This should probably create a child composition of the original
        composition = frameLayout.setContent(parentComposition, children)
    }

    fun disposeComposition() {
        composition?.dispose()
    }

    override fun onTouchEvent(event: MotionEvent): Boolean {
        val result = super.onTouchEvent(event)
        if (result) {
            onCloseRequest()
        }
        return result
    }

    override fun cancel() {
        // Prevents the dialog from dismissing itself
        return
    }

    override fun onBackPressed() {
        onCloseRequest()
    }
}
