I am trying make an app with flutter that adds a block in a page in notion but it doesn't let me use the Text widget as an argument for the text parameter in the ToDo widget. It gives me the error "The argument type 'Text' can't be assigned to the parameter type 'Text?'."
void writeToNotion() {
String userPost = _textController.text;
Children children = Children.withBlocks(
[
ToDo(text: Text("Yo")),
],
);
// Send the instance to Notion
notion.blocks.append(
...
);
}
I tried to just add an empty/simple ToDo() with no arguments and it successfully added one.
void writeToNotion() {
String userPost = _textController.text;
Children children = Children.withBlocks(
[
ToDo(),
],
);
// Send the instance to Notion
notion.blocks.append(
...
);
}
Putting null assertion operator after the Text widget also does not work
void writeToNotion() {
String userPost = _textController.text;
Children children = Children.withBlocks(
[
ToDo(text: Text("Yo")!),
],
);
// Send the instance to Notion
notion.blocks.append(
...
);
}
Below is the program output run with stacktrace
> Task :app:compileFlutterBuildDebug
lib/main.dart:60:30: Error: The argument type 'Text/*1*/' can't be assigned to the parameter type 'Text/*2*/?'.

It looks like there is 2 different classes called Text
here. The Text
in ToDo
does not refer to the Flutter Text
but one from the notion_api package.
To fix you should be able to write this in the imports of that file
import 'package:notion_api/notion/general/rich_text.dart' as notion;
And then use it as
void writeToNotion() {
String userPost = _textController.text;
Children children = Children.withBlocks(
[
ToDo(text: notion.Text("Yo")),
],
);
// Send the instance to Notion
notion.blocks.append(
...
);
}
