我正在开发一个 react-native 移动应用程序，主要用于 android 平台。我最近需要为 react-native-firebase 升级 react native 版本。React-native 版本是0.57.2. 我升级到0.59.6使用rn-diff-purge。这样做时，我需要将 react-navigation 版本从2.17.0to更新3.8.1（但类型版本@types/react-navigation": "^2.0.23"如您所见，我不知道这是否有区别）

升级后，唯一头疼的就是react-navigation。我解决了一些问题。但毕竟，当我远程启用 debug-js 时，导航转换变得非常缓慢。尤其是this.props.navigation.goBack();电话。我尝试给出组件的名称this.props.navigation.navigate("SomeRouter");，但我猜是关于组件已经安装的问题。

为什么会这样？减速的原因可能是什么？我该如何调试呢？顺便说一句，当远程调试js被禁用时，没有问题，当远程调试js被启用时，transitions变成了一场灾难！

这是一个示例组件：

import React, { Component } from "react";
import { BackHandler, Dimensions, StyleSheet, Text, View } from "react-native";
import Image from "react-native-scalable-image";
import { NavigationScreenProp, NavigationState } from "react-navigation";
import { connect } from "react-redux";
import MenuButton from "../components/MenuButton";
import * as types from "../store/types";



interface IProp {
  navigation: NavigationScreenProp<NavigationState>;
}
interface ReduxProps {
  currentUser?: types.User;
  currentCompany?: types.Company;
  currentStore?: types.Store;
}
class Menu extends Component<IProp & ReduxProps> {
  state = {
    UserPermissions: this.props.currentUser.permissions,
    CompanyNo: this.props.currentCompany.SIRKETNO,
    StoreNo: this.props.currentStore.BIRIMNO,

    buttonCount: -1 as number,
    buttonNames: [] as string[]
  };

  static navigationOptions = {
    title: "OliMobile",
    headerStyle: { marginTop: 0, backgroundColor: "#fff" },
    headerLeft: null,
    gesturesEnabled: false
  };

  componentDidMount() {
    BackHandler.addEventListener("hardwareBackPress", this.handleBackButton);


  }

  componentWillUnmount() {
    BackHandler.removeEventListener("hardwareBackPress", this.handleBackButton);
  }

  handleBackButton = () => {
    this.props.navigation.goBack();
    return true;
  };

  render() {
    //console.log(this.renderButtonViews())
    return (
      <View style={styles.container}>
        <View style={{ justifyContent: "flex-start", marginTop: -50 }}>
          <Image
            width={Dimensions.get("window").width} // height will be calculated automatically
            source={require("../../img/OliMobile_logo.jpg")}
          />
          {this.renderButtonViews()}
        </View>

        <View style={{ justifyContent: "flex-end" }}>
          <Text
            style={{
              backgroundColor: "rgb(5, 128, 198)",
              color: "white",
              fontSize: 15
            }}
          >
            Sicil No: {this.props.currentUser.sicilNo} Lokasyon No:{" "}
            {this.props.currentStore.BIRIMNO}
          </Text>
        </View>
      </View>
    );
  }
}
const mapStateToProps = (state: types.GlobalState) => ({
  currentUser: state.User,
  currentCompany: state.CurrentCompany,
  currentStore: state.CurrentStore
});
export default connect<{}, {}, ReduxProps>(mapStateToProps)(Menu);

我不知道 react-navigation 的第 3 版有什么问题，但是将 react-navigation 降级到v2.18.3解决了这个问题。
