What version of Go are you using (go version)?

$ go version go1.13.8 darwin/amd64

Does this issue reproduce with the latest release?

package main

import (
	"fmt"
	"reflect"
)

type t1 struct{}

func (t *t1) Name() string {
	return "tbl_t1"
}
func main() {
	m := t1{}
	rv := reflect.ValueOf(m)
	fn := rv.MethodByName("Name")
	fmt.Println(fn)
        // <invalid reflect.Value> ??????
}

why not get the method ?

You have to use m := &t1{}, because the method is declared on the pointer.
