Base64Codec class
A base64 encoder and decoder.
A Base64Codec allows base64 encoding bytes into ASCII strings and decoding valid encodings back to bytes.
This implementation only handles the simplest RFC 4648 base64 and base64url encodings. It does not allow invalid characters when decoding and it requires, and generates, padding so that the input is always a multiple of four characters.

Properties
- decoder → Base64Decoder
read-only
- Returns the decoder of
this, converting from T to S. [...] - encoder → Base64Encoder
read-only
- Returns the encoder from
S to T. [...] - hashCode → int
read-only, inherited
- The hash code for this object. [...]
- inverted → Codec<String, List<int>>
read-only, inherited
- Inverts
this. [...] - runtimeType → Type
read-only, inherited
- A representation of the runtime type of the object.
Methods
- decode(String encoded) → Uint8List
- Decodes
encoded. [...] - normalize(String source, [ int start = 0, int end ]) → String
- Validates and normalizes the base64 encoded data in
source. [...] - encode(List<int> input) → String
inherited
- Encodes
input. [...] - fuse<R>(Codec<String, R> other) → Codec<List<int>, R>
inherited
- Fuses
this with other. [...] - noSuchMethod(Invocation invocation) → dynamic
inherited
- Invoked when a non-existent method or property is accessed. [...]
- toString() → String
inherited
- Returns a string representation of this object.
Operators
- operator ==(dynamic other) → bool
inherited
- The equality operator. [...]
