Je reçois une erreur sur iOS uniquement:
TypeError: undefined is not an object (evaluating 'this._callListeners.bind')
This error is located at:
in DrawerLayout (at DrawerView.js:161)

Cela a commencé lorsque j'ai commencé à utiliser react-navigation; mais fonctionne bien sur Android.
Voici le code où nous utilisons react-navigation, voici l'application principale dont les importations comprennent les écrans d'accueil et de paramètres:
//imports...
const routes = {
Home: Home,
Settings: Settings
};
const AppNavigator = createDrawerNavigator(routes);
const AppContainer = createAppContainer(AppNavigator);
export default class App extends React.Component {
state = {}
render() {
if (this.state.isReady) {
return (
<AppContainer/>
);
}
else {
return (<Container><Spinner/></Container>);
}
}
componentWillMount() {
this._loadAssets();
}
async _loadAssets() {
await Expo.Font.loadAsync({
Roboto: require("native-base/Fonts/Roboto.ttf"),
Roboto_medium: require("native-base/Fonts/Roboto_medium.ttf")
});
this.setState({ isReady: true });
}
}
J'ai finalement réussi à faire en sorte que cela fonctionne après de nombreuses itérations parmi les solutions possibles.
Il semble que j'ai eu quelques problèmes - avec des conflits de version de paquet et la configuration de .babelrc.
Avec ceux-ci j'ai pu me lever et courir ..
package.json deps:

Et .babelrc dans mon répertoire racine:
{
"presets": ["babel-preset-expo"],
"plugins": [
["module-resolver", {
"root": ["./"],
"alias": {
"_framework": "./framework",
"_apps": "./apps"
}
}]
]
}
J'ai corrigé cette erreur en apportant la modification suivante à mon .babelrc
{
"presets": ["module:metro-react-native-babel-preset"],
"plugins": [
- ["@babel/plugin-proposal-decorators", { "decoratorsBeforeExport": true }]
+ ["@babel/plugin-proposal-decorators", { "legacy": true }]
]
}
