javascript - 反应本机，道具类型失败：提供给`Image`的无效道具`source`

Question

道具类型失败：source提供给Image我的道具无效，我在上传图片时遇到了该错误。我使用图像选择器来选择图像并使其成为组件，但它没有拾取下面的源代码是我的图像选择器 FormImage.js 代码

class FormImage extends Component {
  state = {
    hasCameraPermission: null,
  };

  async componentDidMount() {
    const { status } = await Permissions.askAsync(Permissions.CAMERA_ROLL);
    this.setState({ hasCameraPermission: status === "granted" });
  }

  _pickImage = async () => {
    let result = await ImagePicker.launchImageLibraryAsync({
      mediaTypes: ImagePicker.MediaTypeOptions.Images,
      allowsEditing: true,
      aspect: [4, 3],
    });

    if (!result.cancelled) {
      this.setState({ image: result.uri });
      this.props.formikProps.setFieldValue("image", result.uri);
    }
  };

  render() {
    return (
      <TouchableWithoutFeedback onPress={this._pickImage}>
        <View style={styles.container}>
          {!this.props.image && (
            <MaterialCommunityIcons
              color={colors.medium}
              name="camera"
              size={40}
            />
          )}
          {this.props.image && (
            <Image style={styles.image} source={{ uri: this.props.image }} />
          )}
        </View>
      </TouchableWithoutFeedback>
    );
  }
}

我不知道为什么它显示错误我将在 AddPost.js 下面分享我的 formik 代码

const validationSchema = Yup.object({
  title: Yup.string().required().min(5).max(15).label("Title"),
  des: Yup.string().required().min(15).max(200).label("Description"),
  image: Yup.mixed(),
});

class AddPost extends Component {
  render() {
    return (
      <Formik
        initialValues={{ title: "", des: "", image: null }}
        onSubmit={(values, actions) => {
          this.props.addPost(values);
          console.log(values);
        }}
        validationSchema={validationSchema}
      >
        {(value) => (
          <KeyboardAvoidingView
            behavior="position"
            keyboardVerticalOffset={Platform.OS === "ios" ? 0 : 100}
          >
            <FormImage formikProps={value} image={value.values.image} />
            <Text style={styles.error}>
              {value.touched.image && value.errors.image}
            </Text>
            <TextInput
              placeholder="Title"
              onChangeText={value.handleChange("title")}
              style={styles.input}
              value={value.values.title}
              onBlur={value.handleBlur("title")}
            />

下面是我的主屏幕代码 home.js

class Home extends Component {
  state = {
    modal: false,
    post: [
      {
        key: "1",
        title: "A Good Boi",
        des: "He's a good boi and every one know it.",
        image: require("../assets/dog.jpg"),
      },
      {
        key: "2",
        title: "John Cena",
        des: "As you can see, You can't see me!",
        image: require("../assets/cena.jpg"),
      },
    ],
  };

  addPost = (posts) => {
    posts.key = Math.random().toString();
    this.setState((prevState) => {
      return {
        post: [...prevState.post, posts],
        modal: false,
      };
    });
  };

  render() {
    return (
      <Screen style={styles.screen}>
        <Modal visible={this.state.modal} animationType="slide">
          <TouchableWithoutFeedback onPress={Keyboard.dismiss}>
            <View style={styles.modalContainer}>
              <AddPost addPost={this.addPost} />
            </View>
          </TouchableWithoutFeedback>
        </Modal>
        <FlatList
          data={this.state.post}
          renderItem={({ item }) => (
            <>
              <Card
                title={item.title}
                subTitle={item.des}
                image={item.image}
                onPress={() => this.props.navigation.navigate("Details", item)}
              />
            </>

有人可以告诉我为什么不选择来源：/
