Answer 1

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)
         }    
})
}

AsyncStorage.setItem and this.setState are async funtion, so your console.log() will not be work as you wish. To console you can try

savedata = async (value) => {
  try {
    await AsyncStorage.setItem("myKey", value);
    this.setState({myKey: value}, () => {
      console.log("deneme",value);
    })
  } catch (error) {
    console.log('Store error');
  }
}
