+ *
+ * ```kotlin
+ * val dialog = TextInputDialog.newInstance(getString(R.string.dialog_title), getString(R.string.dialog_hint))
+ * dialog.show(supportFragmentManager, "text_input_dialog")
+ * dialog.setFragmentResultListener(TextInputDialog.REQUEST_KEY) { _, bundle ->
+ *   doSomething(bundle.getString(TextInputDialog.BUNDLE_KEY_TEXT))
+ * }
+ * ```
