You could try to store json as string and later parse json during get

savedata = (username,password) => {
 let value = {'username' : username, 'password':password}   
 await AsyncStorage.setItem('myKey', JSON.stringify(value));
    this.setState({myKey: value});

    console.log("deneme",value);
} 

constructor(){
    AsyncStorage.getItem("myKey").then((value) => {
         if (value){
         let valueParsed = JSON.parse(value)        
         this.setState({myKey: valueParsed});
         console.log("didmounth : ", valueParsed)
         }    
})
}
